Talbert,
I too notice the same trend when I came back. Fortunately, some of the better kits imho could be still found on eBay. Mind you, sometimes at ridiculous prices. Over the past five years I have been buying kits and or collecting plans and manuals for my favorites builds. OneNote is a great tool for collecting info and digitizing it. Almost everything needed for a build still can still be sourced. Just not as easy. With this said, once you have a bill of materials and a good plan almost any plane can be built. We just have to go a little old school and cut, sand, prep and paint our birds like we did a few decades ago. Skills I had to learn include canopy forming from plastic sheets. Making my own fiberglass cowlings etc. The good news is radios. About same prices and better abilities.
To wrap it up. If you can build a plane then. You can build them now.
