Anyone have a good place that can do a drysuit zipper repair? My buddies O'Neill Fluid, (all neo), drysuit has a zipper that has a bad tooth (might be missing by now). As it is close to the fully unzipped end we have just been carefully stopping the zipper short of it so as to do no more damage and leave the suit usable. That and a little silicone seal got him thru the fall, but it did leak. But it will probably only get worse, and once the ice melts in the spring even a small leak is a problem. O'Neill is quoting $150 + shipping to fix it which would end up about 1/2 the cost of a new one. Any suggestions?
