Mario has some 1/4 and some 1/8 5/2 valves. might be worth looking into?...i assume it was you talking to me on msn about borrowning a valve the other day- if so talk to mario because i blew my only spair a couple of months back...and as for the r/c switches on the compressor why not just atatch the compressor to your main link and pressure switch? that way you dont have to think about it when driving your machine.
