Exactly right, there is a very nice looking Pentax MC21 SP on the auction site though for £4850, about as cheap as it gets for a ready to go MC21SP these days...unless like I say you get something that needs more work, in which case by the time you have done the work and sourced any parts needed it will probably owe you more than this anyway.
