Nintendo DS on Ebay - refine search on left when you get there. Update via MrLonghair in the comments: DSi and DSiXL prices are expected to drop by $20 in September. Confirmed on Gizmodo here.
Use an AS Oberkorn analogue sequencer [www.analoguesolutions.com] with your DAW. This is but one of many ways to integrate an analogue sequencer with a computer and other MIDI + analog gear.
The method described here is quite flexible, as any rhythm or pattern imaginable can trigger the Oberkorn via MIDI notes, which in turn can control the variable parameters (filters, envelopes) of attached synths.
For those so inclined, steps are triggered via E, and reset is triggered via F by default."
