I was going to recommend the Carter Ember... Somebody should jump on that.
I shoot an Ember2 and love it. I just got into non-wrist releases a short time ago, and the Ember was very natural and easy for me to learn to shoot BT with. It's very adjustable, and for that reason is the perfect release for a new hand held release shooter to figure out what they are most comfortable with. It's dead quiet (unlike some releases I have shot that sound like a bomb going off in your ear), it automatically resets, and I find the thumb shoe far more natural than any of the designs with a knurled knob trigger... I found I tend to want to punch the releases that have a knob, and I'm not at all tempted to punch the Ember with the thumb shoe tucked into the fleshy part of my hand below my thumb.
I highly recommend this release... it's going to be tough to want to go back to a wrist release for hunting in the fall.
