I've sold a few on eBay. The guns alone aren't worth a ton (unless motorized), but my margins are fine since they're all free. I sometimes sell the circular ammo drums or ammo clips separately since they net more and are in higher demand. I probably should like the monster sniper one on Craigslist since it's going to be too expensive to ship. If you sell them as a lot though, it'll be easy to do on eBay since shipping will be averaged out.
