Greg,
Since I haven't needed a new release in about 3 years, I can't give great info on prices. Try going to their website
www.truball.com. I have talked to the Summers family several times (Ben et al.) and they are very customer oriented. If you drop them an e-mail, I'm sure that they will be happy to help. Make sure that you let them know what size of hand you have (small, medium or large). My hand is small and has no problem fitting my Chappy Boss.
