I agree that lever guns are getting increasingly hard to find. I just bought a 30-30 Marlin lever action after a loooooooong search! I ended up purchasing used in a face-to-face transaction that was listed on a local gun forum known for its classifieds.
I would treat any auction site like any eBay transaction...that is to treat each seller as someone that needs to prove themselves reliable and responsible before I do business. Being listed on GunsAmerica or GunBroker is easy. Following through on promises and communicating well is what separates the wheat from the chaff!
