There isn't much that would prevent me from going after amiga gear. It could be an a500 in a dumpster full of screenings from a sewer plant. I love dumpsters, I've been regularly hopping cans for over 15 years. I still go on weekly dumpster runs. You never know what you'll find in there.
There was this computer shop where I used to hit the dumpster pretty regularly and one day I decided to raid it during the day because the previous night I ran into some other guys who were raiding it. (cool dudes though) I hopped in that sucker and closed the door most of the way and went about my business. I was busy unearthing a laser printer when the door opens. The guy just stared at me holding a bag so I reached my arms out and he handed it to me. Then he just walked off like it never happened. That was the best dumpster ever. I've pulled out dozens of macs, c64's, apple IIs, printers, lots and lots of PCs, monitors, etc.
Sadly never an amiga. I've never found any Amiga gear in the trash nor have I found one in a thrift store either. The last time I saw an Amiga in the wild it was around '93. A lone amiga 2000 sitting on a table in a hallway at school getting ready to be tossed. :-(
