Hey WV Scrounger!
Are you looking for a kit that is easy to build, or one that is more authentic? About the best pistol I've seen or gotten is the Lyman Plains Pistol, they're only in percussion, but they look and feel great! The Traditions Trapper is a decent kit and good shooter and I think they still might be available as a flintlock. I think you can still get either of those pistols in kit form for around $200 or so.
I'll see what kind of prices I can find on those two guns. Like you said, it seems that the prices of EVERYTHING is going up^Up^UP!!!
Shoot Safely,
WV_Hillbilly
PS You can PM me about them later on, if you want to.
