Yeah it's overpriced, but it's worth the features it provides. The ribbon cable inside is about 6 feet long and can not be spliced or replaired. Once you take apart the clock spring good luck getting it back together. When I got my new one I tried to take apart my old one to fix it and make a spare, but it was very fragile and alot of the plastic would not hold together. I don't see how it could be rebuilt to be made safe and reliable.
