The Wildfire uses a SF2280 controller and has posted excellent reviews with all the major review sites. Of course, since it's still fairly new, long term reliability and owner impressions are hard to find.

I just ordered the OWC Mercury Electra 6G 120GB. The benchtest numbers aren't as good as the Wildfire, but it's $70 less and has excellent reviews. Most importantly, it was recommended by some tech savvy guys at work.
