When Sun Remarketing was doing their liquidate-through-Ebay, I picked up five of the Brainstorm accelerators. I forget what I paid. Something like $15 each, I think. I picked up several because A) No one else was buying them and B) I had an eye toward reverse engineering them to learn something about how accelerators are built, and accidentally destroying the subject is a fine tradition in reverse engineering.

That is also where all the new (unused) Mac Plus Mice came from. They sold boxes and boxes of them with 50 to the box. I picked up one and a smaller box of 20 or 30. Now I have more mice than I'll ever use in my attic. I am slowly reducing the supply through sales at $10 shipped within the USA.
