Check Ebay regularly, you missed a Linhof Synchro Compur (£45 inc postage) today, it's a #0 shutter from I think a 105mm f3.5 Tessar (I bought it). Be aware not all Compurs have cable release sockets but they are usually OK and good reliable shutters,
Another option is a Prontor #0 a few (made for Polaroid) have no aperture control so take care to check, there's plenty of shutters available I also have Trikon, Epsilon, AGI. Ibsor, Prontor SVS all modern #0 or #1 sizes. Try and stick to Copal (or earlier Seiko)/Compur or Prontor (press type), some Pronto, Prontor S and Prontor SV & SVS lshutters are none standard designed for fixed lens cameras and cocking/shutter release is coupled through the rear of the shutter.
