I have a YEP-641 euphonium and like the valves very much. No problem for me. If you're not careful when lubricating (oiling) valves and drop one in the casing, you can damage a valve guide or the tacquet. The design of plastic (or whatever it is) makes for quieter valves. I usually get at least a year out of my valve guides.
