I'd be suspicious of super cheap LEDs on ebay -- they may be cheap but they're unbranded and you don't know how long they'll last. And I'd definitely stay away from the ones that consist of 50 normal LEDs all pasted together. Normal LEDs aren't made to deal with the high current and heat you get from packing them together, so their lifetime is anyone's guess. I've been putting in LED spots for my office (instead of 25W halogen MR16 lights). I've tried some off of ebay that (claim to) have Luxeon or Nichia LEDs. I've also gotten some from http://www.ledwaves.com/ http://www.ledwaves.com/. All are pretty nice, but I haven't decided what color temp I like so currently there's a mishmash of cool and warm ones...
