Have you considered one of the Denon carts? Either the dl-110 (which is what I use) or the dl-160 are well reviewed here on A'gon. They're both relatively high output MC carts so they should be run thru an MM stage. The dl-103 low output MC is also supposed to be dandy. I think I'll take a go at one myself to see if it's all that.
Good luck!
