This weekend, I was weak. A TR-606 came up on philadelphia.craigslist.org, single owner, with carrying case, for a decent price. I had bought one over a decade ago for $75 (it was non-functioning). With a little bit of solder, it was functioning again, and I sold it a few weeks later for $250. Pretty good turnaround, but I've regretted selling it ever since. That has now been rectified, and also satisfies this stupid want of a shiny silver noise box from the early-mid 80s.

If Cyclone Analogic releases a decent TR-606 clone with MIDI though, this sucker's going right up on eBay.
