Had one for a 18 months, have the first version (analog, unbalanced) Love it! Use it with a Glyph 500GB HD. Quick easy set up, traveled to Europe with it, carry on luggage.
The Alesis HD24 used to be my Multitrack workhorse...life got a lot easier to multitrack with the Joeco, basically idiot proof operation. Worth every penny, pricey it is, luckily picked up a demo version at $2K at the time. i know (via the Team Blues) you do a lot of recording, buying this kit puts you into another level.
