I was thinking maybe Line 6's toneport? I owned a POD way back in the day when they first came out, and I was very pleased with how they sounded in my computer..
I would say m-audio aswell. I got the firewire 410 and its more then i need and great . I did pay 300 and something $'s for it though but they do have some for under $100 I think.
I was in the same boat as you, and decided to save for a couple of months and invest in something that would last me.
I ended up buying a MOTU Ultalite Audio Interface, I use it on my iMac with Logic Pro and let me tell you it works like a charm I'm in love with this thing. Extremely well built, small, light, enough connections, virtually no latency powered by firewire but it has an AC adapter anyway you name it, it's more expensive than the other interfaces suggested and while I have not tried the other units this one IMO is well worth the cash.
Motu products are definitely awesome contenders. I have an 828mkii, I've owned it for close to five years and have absolutley no problems with it. Fantastic device, with an Adat converter and a set of 8 mic pre's I can get 20 channels in, and 5 different stereo mixes out, great for picky players who want to hear themselves louder than everyone else when tracking. Works with both Mac and Windows, and they have both a firewire version and usb 2.0. I bought it new for $749, not sure if it is cheaper now. MOTU.com - Welcome to MOTU
If you don't need to record more than two things simultaneously, go for the Presonus Firebox. It's decent, affordable, and well supported.
If you need to record more things simultaneously (like a live drum kit) you'll need something bigger and more expensive like Presonus Firepod or the newer one.. Firestudio or some such thing.
The MOTU stuff is great, probably better than Presonus, but if you're not splitting hairs the Presonus will work for your application.
if you got a mac get an apogee interface.. they are absolutely awesome! (and expensive..but you get what you pay for )
if you are on a budget get the presonus inspire 1394.. it can be linked so if you play in a band and every member got their own card you can just add em up and get more channels at the same time. they also have a nice software collection included.
only negative thing i got to say about it is that there is no "analog" controls on it. you have to use the software mixer to control it.. for some that is worse than all the spammers joining in here lately.. for others its no big deal at all
