BTW, on the topic of service etc ... the guy from Ultra Precision (Phil ?) really takes care of his customers. I had a UP-3 valve that got damaged in a crash, with all of the nipples bent and/or broken. I called U.P. to see if I could buy replacement nipples, and he said "No - you're not buying them - I'll either send you the parts you need free of charge, or you can send the unit back to me and I will repair & service it for you and you pay only for shipping, not for parts or labour".

Hard to beat that kind of customer commitment.
