I have the new Johnny Stewart Wireless, that will hold 3 different cards for 12 sounds available during a set. It's probably all I'll need and seems to do the trick! It has a Yellow Hammer that Fox Pro doesn't have, and the Coyote Pup in Distress sounds alot better than the Fox Pro version. But I do like the Fox Pro. I don't know if it's the cool buttons, 600 sounds (like I'll ever use that many) or what the deal is but I really want one. Just can't justify handing over $600 for a new Fury when the $199 I paid for the Johnny Stewart is working just fine!
