Anybody in this hobby to make a buck, instead of enjoying it, misses the point. Parts sellers are an exception, but they buy-em breakem u, and we need-em.. It is the love and appreciation of it all. Hell, shooting trap, I can go through $5,000 a year on fees, shells and travel expenses. I used to race SCCA and it costs an insane amt--all down the drain too. Car restoration is similar--black holes. My old cars return pleasure that is far in excess of value-- and it is 1968 all over again for me. Buying a gun and throwing some resto pieces on it or even indulging yourself in more advances projects that may lose some , is just part of it. I'll bet that most can nearly break even in the short run, but in the long run--the appreciation and pheromones that your brain gives you from the hobby, and from the ownership pride of a fine piece, and love of it all, well, it keeps you healthy and you may even earn a buck.
