DTXplorer. Got a year ago as a Christmas gift. I don't use it anymore and won't have room for it in the apartment I'm moving to. I'll include the throne, two sets of drum sticks with the rubberized "no slip" grip, and the midi-to-usb cable if you ever wanted to record midi drums through a program on your computer. There's a click option to keep time and an auxiliary input to plug in an mp3 player and play along to.
It goes new for $700, I'm selling mine for $400.
E-mail me at mwo1983@gmail.com or call 802-363-2089 if you want to take a look or try it out. I'm in Winooski.
