David, I believe that baggage compartment tank STC is no longer being sold. However, the Flint Aero wing tanks are still being sold and installed.

I recently called the company. They are actively selling kits, but no longer doing the installations themselves. They can recommend an installer in the customer's area.

I've considered this option. Downside: add 34 lbs to your empty weight. Lets see: 200 lbs (me) + (23.5+23 gal x 6.0 lbs/gal) and a bit of luggage = about 500 lbs. Sounds good, except my useful load would then be only 465 lbs. This is the main reason I haven't gone down this road. Of course, you don't have to run full tanks, but then why get them if you can't fill them?
