Last summer I saw some Amiga stuff locally advertised. Ended up picking up a WarpEngine 040 and X-Surf II and some other stuff for 40 bucks.
I asked the guy if he had any other Amiga stuff and he told me he just tossed an A4000 in the back of his truck for a run to the dump....snagged that for free!

It was complete and the case was in near mint shape... lucky day!
