Wanted: Olympus UTP530 and BH2-UDF

[mcfluffin]

Want a few accessories for my BH2-UMA, mostly the UTP530 as its the last piece I need to do DIC. I found some sources for these but they are asking more than was hoping to pay (250-300 USD each). Maybe someone can point me to somewhere where I might get a better deal or has one to trade/sell? I am willing to pay cash but also have a large stock of surplus microscope equipment (Olympus Neo SPlan, Nikon BD, observation tubes, etc) for trade. I am in USA if it matters. Also I'm not opposed to trying to re-machine a compensator from another microscope if that will work just as well and save the wallet.

EDIT:
I bought this:

although I have no idea how good Lomo stuff is. Will see if I can fit it but I'd still be interested in original parts if availible
