So I'm about ready to buy an M-Audio ProFire 610 (http://www.m-audio.com/index.php?do=...9e3b31383ca0ca ) which I will mainly use for recording vocals into my computer, and occasionally my synthesizer.

I'm wondering if there are any comparable quality products that are in the same price range or lower? Anything with a similar number of inputs, and good quality preamps? Thanks.
