Picking up one of these tomorrow. Can't wait...
I've been GASsing for one for a while now - amongst other things I need the exercise (that's my excuse and I'm stickin' to it). An electronic kit also lets me practice with 'phones, keep band practices at sane levels and I can still use all my EZDrummer drum kits when I'm recording.
I got it for an excellent price on the Bothner's Birthday sale - basically half price. The newer version with all mesh heads was a bit out of my price range, but this is both expandable and upgradeable.
