I've had a M-Audio ProFire 610 for a year or two now, and I recommend it highly for a budget (but decent) interface.
The preamps are decent, which is generally the most important thing, and it also has the ability to run at 24Bit/192KHz. Most people wont use the 192KHz, but its nice to know that its capable of it if you ever needed it.
I regularly use it with Cubase and Logic, and when I bought it it had the bonus of being compatible with Pro Tools (M Powered) if I ever needed it, although that isn't an issue with the new version (9) as the software no longer requires specific hardware.
Cost me £240 here in the UK, probably work out cheaper over in the US, and that was a year or two ago as well.
