I get a kick out of his wall of shame. I forgot about his service, been around forever. Valuable resource, think I've bought batteries from him on Ebay. I agree though, that if you aren't someone who has the skills (or the ability to pick up simple skills quickly), $50 is a small fee for a repaired key.
Still not sure it's anything like medical brain surgery to open up one of these keys. But hey, maybe I'll give that a go if the wife starts being un-reponsive to my inputs.
