Made this the other day. I think it cost around $80. It is loud and clear. Same as one on Varmint Al's website but I mounted the speaker on a piece of plywood thats is fitted to the bottom of the bag. I use my ipod to play mp3's. Going to go in the morning and try it out. I'll let y'all know how it works out. Is there any way to get Foxpro sounds in mp3 format? Thanks, Nick
