There are a few options, there. Behringer makes one...UM2, I think. Lexicon Alpha should fit in that budget. Both have single mike preamp and instrument in. I'm sorry, you didn't mention a guitar, X did. Anyway, those will get an xlr into your computer. Can't vouch for the audio quality on either, but I've heard little bad about either, either. Both are available @ amazonUK. Both get mixed reviews. But I've never seen anything on amazon that didn't.
