Jason,
Releases are kind of like bows, you have to shoot a few to decide what you like. I have a Tru-Fire Hurricane series, that was about $60 and it fits me. There were several cheaper and more expensive, I shot a host of them, and then decided on what I really wanted. Many guys like SCOTT Archery products, esp. the "Little Goose" seems to be one I hear a lot. Shooting fingers will NEVER give you the consistency of a release though, you just can't release as consistent and perfect as a mechanical release.
