Go to gunbroker and click the "buyers" tab at the top then go to "find an FFL". You can enter your zip code and it will give you a list to all of the FFL's that have submitted their license (which is a quite a bit) to gunbroker. It will list them in order of closest to you but it will also give their prices.
I use Geaux shootin most often, but have used LA gun and Reloading. I do business with Pelican Pawn also, never a transfer. All are less than $20 and great guys. I had a bad experience with City Pawn on Florida...
