Promate is in fact a full line and purchases their equipment from the same suppliers that many of the big industry names purchase from. The biggest difference, price! As a Promate dealer, I service what I sell. I believe that you will see a lot more of Promate the longer they are around. Having only been selling equipment for about 6 years, they are doing quite well. Just remember, the folks they purchase much of their line from have been manufacturing equipment for the dive industry for over 20 years. I purchased the line for my student/rental equipment as well and am quite pleased. Wouldn't have invested so much in a line I didn't find to be a quality product. Everything in the promate line comes with a 1 year warranty and I extend your warranty on your first stage every year you get it serviced. The "lifetime" warranty you hear from other manufacturers is dependant upon you getting your reg serviced within the 365 day window anually. RE: Free parts kits. Some manufacturers even offer free parts with your anual service within this window. Well, considering a promate regulator costs hundred$ le$$, thats a lot of making up to do with $18 parts kits!
