You know as well as I do, Dan, airguns are like beer. You don't own them, you just rent them for awhile :-).
I, too, have "owned" a bunch of guns, started with springers, went all PCP for awhile, then recently went back to nothing but springers. I have just 4 right now, a Gamo CFX, a Diana 34, an R9 GF, and a TX 200 Mk. III, all .177. Oddly enough, the TX is the least favorite of the four, and I'm already thinking about a replacement :-). Problem is, the short list doesn't seem to have anything on it! I'm toying with the idea of a vintage match rifle or a Diana 54, but it's only toying at the moment. I also have a friend (wink,wink!) who's jonesing for a TX, so I might have to figure out a way to make that work. We've done it before :-).
My focus is shifting to working on airguns, I just picked up an older Grizzly 12x24 lathe, and I can't wait to get started with it. I have several projects I want to do on my CFX, after that, I'll probably be looking for beater rifles for practice. And with that, I have a lathe sitting on a trailer, time to go start setting it up :-)! Later.
