Even though Amiga gear is rare, it does pop up from time to time. I have found many bargains at local flea markets. It is a shame that many users simply binned their machines & hardware when M$ began to dominate the home computer market circa 1993.
This year I spotted an Amiga 500 (with few games) at my local GameStation store. They shrink wrapped it and labelled it "retro console" for £50!
Today, I picked up three PSX bargains. Warcraft II, Bomberman and the movie tie-in The Fifth Element. All in excellent condition for only £6.
