I own a couple T/C caplocks, and they cost a lot used now. But where are all of the cheap ones by Traditions, CVA, and others?

I'd like to have a few that are shooters, and to use as wallhangers. They make good wall art. The average person won't know the difference in a custom gun and a cheap foreign made one.

Also, one question: Where can you mail order real black powder now? I use to 20+ years ago, but I have no sources now.
