Music Hall mmf-5 vs. Rega P3

I know the high praise both of these TTs usually get puts them solidly in the best-bang-for-the-buck category, but in a head-to-head which one is the better...buy? build? sound? I suspect the P3 may get the most nods, in which case, what changes or mods would the mmf-5 need to go through to match/exceed it? Thoughts?
