USB is fine. s/pdif is like the High Def of sound... Wait it is! but it might not be compatible with your computer? USB is fine, I use USB and get very nice sound so don't bother with the extra money.

ok thanks
i wasn't sure if the spdif was going to "sound $300 better" since that is how much an spdif interface would cost and I am happy with the quality that I get from the usb

It really comes down to the same reason people buy Gibsons over Epiphones.

How much are you willing to pay for the extra quality? For some people, yes, it is totally worth it. For others on smaller budgets, or who care less, then it might not be.
