Went with the MA40 hubs with ultegra 600 hubs (FH 6500 rear and HB 6400 front) from ebay. There's a guy who builds wheels that said he'd do €60 per wheel with DT swiss spokes. The plan is to get a shimano 9 speed11-34 cassette so a chain and long derailleur will also be needed. Should be on the road in a couple of weeks if all goes well. I'll put up some pics as soon as its on wheels. Thanks again for all your help.
