JDug,
If my humble opinion counts for anything, do whatever you need to make your hobby fulfilling and let the others do what they need. If one is a purist and only places value on those things wrested from the soil with sweat and toil, fine. However, if one's hobby places the value on the relics themselves and the history they represent any way that they can come by them, that's great too. The wonderful thing about a hobby is that it is the hobbyists themselves who define their own hobby, not others. As I mentioned in an earlier post, I'm obsessed by engravings, and yes, I get a greater thrill from finding a special piece on my own at a local sale, but if there is some artist's work I crave and I can only find it by "cheating" (ebay, ect. lol), then that's what I'll do. My obsession is for the art, not how I come by it.
