Take a close look at this example built by John Youngblut. You are quickly charmed by fond images of an earlier period in aviation. Then you look deeper, noticing its shaped wood struts, leather trim, and classic analog guages. This draws you in further and I watched people get closer and closer as they examined the detail.
All that leaves out how well it flies, which developer Nick Pfannenstiel reported was the #1 appeal of the airplane. So after enjoying an easy, relaxing flight in your Jenny, you land to be swarmed by people who believe they've just witnessed a piece of history fly into their lives.
Jenny began life as a Curtiss, was recreated in scaled down form by Early Bird Aircraft (Gen 1) and kits are now manufactured by Timber Tiger Aircraft, which has reimagined again in slightly larger scale, better fitting modern Americans.
"Thousands of surplus Jennys were sold at bargain prices to private owners in the years after WWI and became central to the barnstorming era that helped awaken the U.S. to civil aviation through much of the 1920," according to Wikipedia. "It was the first airplane many people ever saw," said Timber Tiger Aircraft.
Owning an original would take a substantial investment, far out of most budgets. Yet Timber Tiger's updated and improved Jenny — one that faithfully reproduces an original in slightly smaller form, therefore requiring less engine — is far more affordable.
Early Bird Aircraft created their "Generation 1" Jenny at two-thirds scale. The "Generation 2" Jenny by Timber Tiger Aircraft is a three-quarters scale replica featuring "improved hardware, improved documentation, more accurate replica looks, more advanced kit preparation, and reinforcements in key areas," explained Nick.
A few years back, Timber Tiger made a splash with its entry of a 95%-scale Ryan ST, an iconic aircraft of that postwar golden age of aviation. 
Jenny is offered in a variety of kits. Start with a basic kit (for experienced builders) for $6,900. A group of extra kits can be bought separately: quick-build wing kits, a snazzy louvered engine cowl kit, and several others. All that's lacking is an engine, prop, instruments (and perhaps an electrical system), tires and tubes, plus covering and paint.
Nick advises that for most buyers and certainly first-time builders, the complete kit involving some quick-build assemblies is the wisest choice that will ultimately save them money while greatly easing (and making more accurate) the build effort.
Here is another entry that qualifies as affordable (though that means something different for each person reading). "Estimated average cost to build to completion is $25,000 to $45,000," said Nick at AirVenture Oshkosh 2023. Here's how that breaks out.
Starting with a base kit for $6,900 plus engine — likely used/rebuilt — plus some hardware components supplied by the owner ("nothing particularly hard to obtain"), Nick indicated an experienced builder could get airborne for $25,000.
Think about this. If you land your Timber Tiger Jenny at any GA airport and taxi up to the ramp, you might have trouble getting out of the cockpit for all the admirers that will assemble around you.

We simply had to do a video interview with the developer of the 1930s-era Ryan ST because of its fascinating history and its handsome good looks. If you love vintage aviation, this should grab your attention as it did mine.
Nick Pfannenstiel is a young developer with a mission, to create or, more accurately, re-create the Ryan ST. He began the design phase of his 95% scale Ryan ST in June 2015 and construction began in early 2016. By 2018, you see the aircraft is nearly finished form.
Ryan's ST featured two open cockpits in tandem seating with a semi-monocoque metal fuselage. A main steel ring forms the backbone of the Ryan ST replica but most of the fuselage uses aluminium alloy
The project is not merely a personal fascination for Nick. He will be selling a builder's kit and specifically chose the 95% scale to make it enough lighter to use modern engines. Nick explains this further in the video. He expects first flight fairly early in 2019.
He plans to offer motor mounts for either D-Motor LF-39 or 
Thanks to Nick's effort, you won't have to spend nearly that much; he has established a price for his kit: $31,890, not including considerable effort to polish the aluminum as you see in the nearby photos. A quick-build option for $3,000 will likely be popular.
"We estimate that if a builder really splurges on the kit, he or she should be able to get in the air for less than $75,000," Nick estimated. Build time will exceed 1,000 hours but this is modern, CAD-designed kit.
Nick and his Timber Tiger Aircraft company are located in Brighton, Colorado. 
The first Ryan ST flew for the first time on June 8th, 1934 and production began the following year, when nine aircraft were delivered. Production rates remained low — about one aircraft every two weeks — but this changed in 1940 when deliveries to military forces began in earnest to support the war effort. Total production of civil and military aircraft before WWII numbered 315. Another 1,253 military versions were produced in '42-'43 totaling 1,568 aircraft of all models.
