I bought it on thomann.de, it took me a little over an hour to set it up! Tidily packaged. Price: about $650.
I wanted a kit that didn't have the poor-quality "white" pads featured on the mps-100 and mps-300.

First Impression:
The structure is rigid, but the plastic screws don't seem to be very solid...watch out not to turn hem to hard! The sounds of the module are really cheap.

20 preset kits, 10 customizable kits, 215 voices.

A nice surprise is that the pads are of good quality, they respond well to the hits and rebound fine, and that's what counts to practice at home. The sound intensity corresponds perfectly to the hit, but I haven't tested it with MIDI yet.

There aren't many models at this price point. Either you get something cheaper, a down-market kit or you go for the yamaha dtxplorer for 900-1000 bucks.
Having tested both, the yamaha module is certainly better, but the pads are the same.

Excellent value for money. It's a good compromise between the millenium mps-100 and the yamaha dtxplorer with the same pads for $250-$350 less.
