This is an old thread, but still relevant. Just follow Claven2's advice and look for good condition.
RC's aren't as easy to find now as they were a couple of years ago, but I still feel they're a bargain when you can find a good one. They aren't high priced like the all matching rifles, but they're still interesting, historical rifles and can make great shooters.
They almost have a collecting persona of their own now and are nothing to be ashamed of.
