Curiously, the used C&B revolvers very often sell for more than they can be had new at places like Cabela's. However, many models are no longer produced and used or second hand is your only option. e.g., Rogers & Spencer. Then again there are plenty of used C&B revolvers that sell for bargain prices as well. I have purchased many C&B revolvers on line based on posted images. The majority of the time the revolver showed up in better shape than I expected. Many of the small nicks and scrapes that show up vividly in a good close up image, are barely discernible to the naked eye, and a lot of time it turns out to just be a mark that wipes right off. Most folks can't seem to get a decent image of the bore though, so there could be surprises. I don't worry about return policies on Gunbroker. Its an auction site so I make a judgment and live with it. So far, that has been overwhelmingly successful for me.
On second thought, you should stay away from used C&B revolvers on line, that way I won't be bidding against you.
