[LAU] Card advice: M-aud. Fasttrack vs. Rol. UA25EX vs. ?

Hi all, I'm in the market for a USB audio interface and I thought I'd come to the well for advice. Right now, the main two contenders in the race, because they're available at my local music shop, are M-Audio Fasttrack Pro and Roland/Edirol/cakewalk (they keep rebranding it, I think) UA25EX. Because I've seen them come up on this list, I know they work fairly well with Linux, but I was wondering which you would recommend, or if there is another major contender I should know about. My needs: - Works near flawlessly with Linux! - 2 channels in / Stereo out - reliable 24bit/48khz with "decent" preamps/converters - Integrated Midi would be nice, but isn't absolutely necessary - Phantom power on at least one input. - $150-250 price range The UA25EX is slightly more expensive than the M-audio, is it worth it? Also, until recently, the Tascam US122L was in the race, but I found out that the "MkII" is no longer class-compliant: can someone confirm this? All advice welcome. Thanks, S.M.
