I've been intrigued by some of the import ribbon mics, like the Nady line:

RSM-1, the

RSM-4, and the

RSM-5.
Another that really seems like a possible keeper is the
ShinyBox 46. A regular poster over at the Womb has said nice things both about the mic and about their customer service.
I haven't USED these mics, or any ribbon for that matter, but like I said, they look to be a cool alternative...
