Shimano BB-UN54 in 110mm. If you are really worried about it, use the 107mm one.

If, after all your careful calculations, the chainline on paper is off by a few millimeters, don't worry about it. I've used the above Shimano bb with a Sugino crankset and Formula hub and the chainline is dead quiet.
