if u get a toneport by line6 u can always just use a dynamic mic or condensor mic to do your vocals. external sound cards are the way to go guys, i keep tellin ppl it, back when i was setting computers up for ppl, they'd always ask to have the best soundcard put in like a creative audigy 2 with a front bay for the inputs and so on, and the sound quality wasn't as good as an external asio driven unit, because external unit's don't tend to suffer interference from the computers internals like the fans and the electrical currents etc.
