What was the best drum machine ever made in your opinion?

speaking of sequential, not drum machines, sequential alum dave smith's evolver is, like, the greatest toy ever. i mean, it's hardly a toy - pretty effing powerful little monster, really. but at $500 it's practically priced like one... sure wish i could afford me a polyevolver w/ keyboard!

that evolver keyboard looks nice...just saw a Pro-One at Main Drag in Williamsburg, serial number 36..for 1000 dollars.
