Check driver support before you buy from m-audio. Go to the above web site's down load page and see if they support your version of Mac OS X. (Hint 10.5.6 is not supported.)
Most stuff will work fine but corner cases don't, like using two audio interfaces at ones or the higher speed setting.)
This applies to all companies not jut m-audio. Check driver support on the companies web site BEFORE you buy.
To the OP: The problem is not "Are there any" but that that are many dozons of them and researching them all is time consuming. There must be two dozen then would meet your needs
The first question is how much you care about audio quality. Are you one of those people who say that Vinyl has better sound quality then CDs and you want to capture that quality. Or maybe you just want listenable recording and intend to save them a 128K MP3 files on an iPod. How you answer this question will determin if you can use a $40 interface or if you will need to spend $300 or even $3000 if you are the "true audiophile" who buys the silver-plate speaker wire.
EDIT:
This web site will help. But (1) the list prices are MSRP, not "street" and are way high and (2) the web page does not address audio quality only features. You will have to read the specs. Most people would want at least 96K sample rate and 24 bits for recording.

And then how do the jack plugs connect to the M-Audio Fast Track Pro? I dont see any suitable inputs.
All pro audio equipment is going to be using 1/4 inch TS or 1/4 inch TRS connectors. The RCA jacks are a consumer audio thing used for home stereo and TV sets. The pros use the larger connectors because they are more robust.
Also you will find that in the pro audio world many of the signals are "balanced" while home audio mostly uses unbalanced signals. OK so how to connect it up? Tghe places that sell the audio interfaces wil also offer about 100 types of short adaptor cables. After a while you will collect box loads of these. Check out the local Guitar Center or Sam Ash retail stores or on the web Sweetwater.com. You will need a set of RCA to 1/4 inch TS cables or the correct length. I prefer simply buying the corect cable to stacking adaptors but they also sell 1/4 inch plugs with RCA jacks on them. For the most part you can directly connect line level balanced signels to line level nbalanced. There is a 3db (or is it 6db?) level difference but that's within range of the interface's gain adjustment.
