Emagic Emi 2/6 Options

[analog tara]

hi there

i'm setting up a studio for powerbook g4 and am trying to sort out which sound card/midi interface to use. i'm planning to use logic (& maybe some protools) for sequencing/audio. i want to spend under $500 for the sound card & midi sync.

so far, emagic's emi 2/6 looks promising for my price range, along with the mt4. does anyone have opinions on these? or testimonials on how well this setup works?

i'm wondering also about m-audio's quattro...

and of course other product suggestions are welcome...

thanks for the help
