StarDestroyer.Net BBS

I'll admit, I've been watching Macs for a while now, and one program that's caught my interest is garageband. It looks like a fun tool, and I'd love to play with it a bit, but I simply can't justify getting a new computer just for one program on a whim, so I was wondering if there was any sort of PC version, or a similar tool for PCs that did essentially the same thing.

The only PC one I know of is Smart Sound and its expensive... here

It's still cheaper than buying a whole new computer, and at least there's a demo to see if it's worth a damn. Thanks for the info.
