The Whisker Biscuit is a well-know rest with a good rep. I have a compound set up with the Fishook rest by Muzzy. I like it alot. It's tough, inexpensive and easy to adjust. I've only heard of one guy who didn't like it because he said he couldn't get it tight. Mine has never come loose and I've dropped the bow numerous times and have never had a problem with it.
The Wave Rest is a good one too. Easily adjustable and relatively inexpensive.
