Ebay seller "Timarca" has an excellent track record as far as I'm concerned. He's done several valves for me and all are still working just fine at a fraction of the cost of new ones. I've seen his valves fully disassembled and he does the job right. He also has more parts available such as a steer box repair kit, and some new user rebuildable hydro valves that come with C-clips that allow you to do all future repairs for just a few bucks.
It's a good thing to support these cottage industry guys, they keep our hobby going.
