i have one. dunno about the bugs, but i have encountered some weird behaviour. loadsa happy customers though. and serious thump. i think the kickdrum is the wicked thing on this thing!!
but actually i would either buy a machinedrum, or one of those electribes you can put your own samples in or wait for the xbase 999. or invest in something different than a drummachine. like a nice synth or something. i dunno if you need a drummachine nowadays, tbh. of course you don't need a real synth, either ;)
