audio interface to use with mac pro and logic?

[eltico]

I am fairly set on purchasing a mac pro desktop and Logic software to use for recording music. However, i am unsure of which interface to use in conjunction with them. I was previously thinking of buying a digidesign minibox, but now I don't know if that is compatible or the best option. Is there an interface that works best with the mac pro/logic setup? To limit the options, I really only need a small interface (like the minibox), as I will be recording only one instrument at a time. Thank you.
