I have just started shooting compound and I am currently using a truball wrist release.
I am interested in trying a back tension release without risking too much money in case I don't get on with it. I have found a website in USA
http://www.zenitharchery.com/x_cel.htm that sell very reasonably priced releases that look to be nicely engineered. They also sell a CD Rom on how to use them. I can't seam to find any shops in the UK that stock them.
Has anyone tried them? How difficult are they to use? and how likely am I to end up with a broken jaw

?
