I want to record myself singing. The recordings don't need to be great, as all I want to do with them at the moment is turn them into MP3s and upload them to the Web; they don't need to be CD-quality, let alone asking-people-to-pay-money quality. But it'd be nice if they were good-ish.

What I've got: a Mac, a copy of Audacity... and, er, that's it.

Audacity will record off the built-in mike, and its noise-reduction function is quite good if you don't overdo it. But the best I can produce at the moment is something that sounds as if I'm singing into a bucket (the fact that the Mac is sitting on a desk may have something to do with this).

So, calling all MySpace and Youtube types: what's the absolute bare minimum I need? Is a decent recording going to be possible without too much outlay? Or is a day in a studio going to work out cheaper?
