If you've got a DVD burner on you computer, then consider the Korg MR1000 DSD recorder. It'll record at 1-bit 5.6 mHz, which is the ultimate for recording live and for archiving. You then have the choice of burning a mp3, mp4, Redbook CD, HDCD or DVD-A.
I came very close to buying the Alesis for its convenience, but the I jumped at the super resolution of Korg. It's an incredible machine. See my review over in analog reviews.
Of course, it's not worth the extra money unless you're going to use the extra resolution.
