Ah, thank heaven for Ebay. I sold my Dr. Rhythm DR-55 analog drum machine and my Dr. Rhythm DR-660 sample-based drum machine to buy this hot little number in the spring of 2001. It's got a ton of great sounds, it can go lo-fi due to the built-in effects, and is easy as heck to program. It includes a few features that the DR-660 didn't have, but they are essentially the same, so I needn't worry about a great learning curve. Mostly I'll trigger this from my DrumKat. It took less than 3 days for me to yank it unceremoniously to the ground, breaking the left/mono out. $65 later, it's now stored in a safer position in my cramped home studio.
