I have had suck luck before.
Was able to acquire 3 Amiga 4000D systems for a whopping 100 euro. 1 was maxed out with a Cyberstorm mk 2 with 68060 and SCSI + Retina Z3 and Tocatta.
Recently I managed to acquire for 30 euro a Picasso 2 and 4 with Concierto and Pablo and a Prometheus PCI bus board. With some other bits and bobs.
Then I had luck with acquiring some Amiga 1200 systems with a Blizzard 1230-mk4 in it with co-processor for a whopping 50 euro a piece.
Also payed 45 euro once for a BlizzardPPC which was defective and I managed to repair it.
Sometimes you have luck and meet a person that doesn't want the hardware to end up in the hands of dealers/sellers and don't want a {bleep} load of money for it. They just want the hardware to end up with a person that actually uses it.
