New to Mac Music...making a list Options

[bnun]

I've recently purchased an iMac G3 and I would like to start recording my own music. I won't be doing much MIDI stuff. I'll mainly be recording guitar, percussion, vocals through a Shure SM57. I've read a few of the posts around here, but I still need a little clarification about what all I'll need. I'm not looking to go all out, I'm trying to start small.

I've ordered the Pro Tools Free CD, so I'm assuming that will take care of my short-term needs for an application (8 audio tracks should be fine for now). So, now I think I just need a way to get sound into my iMac. I've got 2 ideas as to what might work, so please let me know if I'm way off base.

1. Behringer Mixer - http://www.musiciansfriend.com/ex/shop/rec...1661?pid=631222
This is a little 6 channel mixer. I have seen the iMic, but I wonder if I could run the Mixer into the iMac via the iMic? Could anyone that has experience with this please help?

2. M-Audio Quattro - This is a little more expensive, but from what I understand, I'll can just run my mics into the Quattro and it will hook straight into my USB?

I greatly appreciate any help you folks can give.

Thanks,
Brandon
