Hmmmmmmmm.
Cubase : good.
Zoom: bad.

There are plenty of other software packages out there that have Cubase LE bundled in. If I were you and I was just starting home recording, I would buy Cubasis VST and Line6 Guitarport. Both of those will not cost a lot more thatn the Zoom but will be infinitely more flexible. After a year or so you will know enough about Cubasis to decide whether you want to take the plunge and go for Cubase SX. You'll also find out whether you are happy to stick with digital amp modellers or take the BIG plunge and start investing in hardware. IMO Guitarport will help you create excellent home demos and it is designed for pc use.... unlike Zoom technology which ain't that good at all.... Either that, or start saving now for the real deal, but depending on your means.... that could take a LOOOOOOONG time!
