Personally, I bought a cheap one to see if a like it, and how it felt to shoot. I ended up loving it, and i shoot a lot tighter groups now too! I also use it for hunting, which is another reason I went the cheap route because i didnt want to take the chance losing an expensive release. I went with one with a caliper head so it would hang on my d-loop while hunting. I would suggest either getting a cheap one at first to se if you like it or getting one that fully encloses. One thing you that will change is your anchor point, so that may take some getting use to.
