I've really enjoyed the kit building tales from the PRA. I, too, have been a kit builder for many years and still have a working Heathkit Digital clock from 1973. They made good products. Lately I've been playing with Arduinos and Pi's. I'm not very good and they are a real challenge for me but I persist and my persistence has yielded some working projects. In the process I have a pretty good inventory of electronic components. Like Terry, WB3EVZ, and others have said, it's expensive to buy a single component, so I always ordered more than one. When the transistor costs $0.75 but $10 to ship, I bought 10 of them. Sometimes even more. So don't be shy about collecting stuff. Who knows, perhaps someday we'll have a PRA swap meet.
On another note, while looking for a definition of a Q-code I stumbled across a QSL.net website on the Origins of radio terms. Very interesting read about the development of Morse Code and radio terminology. In the first paragraph is a credit to another site--www.ac6v.com.
You just have to go to this site! The "CHOOSE YOUR AREA OF INTEREST" section item #21 has another link to KITS--lots and lots of kits.
Surely you'll find one that looks interesting.
Have fun
