Try a Crit'R-Call. Comes with a great set of instructions and like 4 extra reeds to customize the sound. It is loud as hell and works great. I think I got it for like 12.00 at Wholesale Sports.
Also, I would recommend you stick with open reed calls. I have called in very few with closed reed calls, and that's only when I was doing some real trickery with my hands and diaphragm. Learn the open reed calls, they are way more versatile. You can also put a rubber band on it and it's just as easy to use as a closed reed.
Electronic or Digital calls don't have to be expensive. I use the Cass Creek Big Horn speaker (got it $30 locally). Use a $25 MP3 player from Wal-Mart (make sure it has a "repeat" function). And downloaded all my calls for FREE from www.varmintal.com and www.mscustomcalls.com . Here is the link for the speaker. It works great, has a 75 ft. cord, built in amplifier, and is completely controled from the sending unit (MP3 player, iPod, etc.)
I gotta put in the word for Sceery calls here. I have used them since I got in the game and they work well. The AP-6 is a bit call that really produces some great sounds. High and low pitched sounds. I have called in ALOT of critters with it. The AP-7 would be my next favorite Sceery call.
