Don't bother with that.
Get a respectable computer with some extra ram and an audio firewire interface.
Get either
Ableton Live, or
ProTools LE.
Then just get the plugins (or
Reason) that are specific to your needs. If you are need good acoustic sampled drums, look at
DFH, or
BFD. For guitars, maybe
Guitar Rig might be useful.
This type of setup is way more friendly and powerful than something like the 2480. Just download the demo of Ableton Live and you'll see how easy it is use.
