I agree with NZshooter having just returned from the fourth gun show in as many months. The people were friendly today, but it's always a gamble to see if the show has what you want and the prices today were very high. Even when "bargained" down the prices wouldn't be very good. I've bought several guns on GunBroker and AuctionArms. Just watch some of the first time prices, the feedback, and look at the pictures/descriptions very closely. I put in the price I'm willing to pay and walk away from the computer.

AuctionArms has the Haggle feature which is kind of neat. One time I was the high bidder but didn't reach the reserve price. The guy emailed me and asked if I'd come up $5 more dollars, I said sure, why not and got the gun for way less than I've seen at the shows.
