There are many manufacturers. Its what you want and the price ranges vary also. Personally I went with LEM. One company, fairly good name, good product, although I have heard some negative comments about their CS dept. I highly recommend you get steel gears on your stuffer, nylon or hard plastic wear and break. Make sure whatever you buy is an establish brand because you will want to buy accessories later down the road or maybe even get repair parts.
Probably these days LEM, Cabellas, and maybe Great Northern would be the most common brands.
I highly agree with Crazymoon, get two toys instead of buying the stereo, CD player, turn table, equalizer combination, unit.
