I know a lot of guys make their own callers using CD players and a lot use MP3 players. Why not have the best of both worlds? I never hear of anyone getting a sony walkman CD player that reads mp3 cd's as well, i picked up an off brand (emerson or lennox or something) that reads mp3 and cd's both and it was about 20 bucks. You should be able to put about 130 sounds or so on a CD i think. Just a suggestion for the guys who want to have a whole bunch of sounds in mp3 format but still have a ton of CD's laying around the house they feel guilty not using.
