ISIS bottom bracket suggestions

Have had a friend offer me Zipp 300 cranks. Great cranks but am stuck w/ an ISIS bb if I take her up on it. Any suggestions on the best possible bb in this situation? FSA Platinum pro titanium looks pretty good but there are many other options. I figure if I get the best ISIS bb then it ought to be fine even if I need to replace them a little more often than the new bbs.

You could use the Zipp 185 Bottom Bracket:

250 bones for one, but matches your cranks.

Have you used it? I can get one on ebay for like $100. But I want a personal experience kind of thing...
