Thanks for all of the info. It seems to be unanimous for the Monotribe.
I will probably pick one of those up as well but I will wait for one to show up on the used market.
This purchase will be strictly for on-the-go jamming/noise making with a Kaossilator, DS-10 and stylophone. For some reason I want another pocket-sized battery-powered box to make it a foursome.
I also may wait until a second iteraton of the Monotribe to come out - somethign with more flexible drum sounds.
