Rob, who got booted from here a while back (fourstringdrums), just bought himself a set, and he posted them along with an ok soundfile over on ghostnote.
Interesting design, pretty clever. Rob's kit is almost a hybrid between a normal nesting kit and a cocktail kick; his pedal is inverted so it plays the bottom head the floor tom (which is also his bass drum). It's a nifty little setup he's got. check it out.
