I'm amazed how many people are missing the point with this item. You do not buy a brand new vintage computer to use. If you want one to use, you buy a $50 second hand one. People buy NOS computers of this age as collectables. I would bet good money that this A3000 will never be taken out of its bags. The second you turn on/test an unused vintage computer, its value drops 70%.
I am an Amiga enthusiast but I also collect brand new vintage games consoles, and there is serious demand for them. A brand new, unused SNES is worth around $500, where as a second hand one is worth about $40. So there most definitely is a market for these, and I actually think the price was very fair. I would have paid that for it if they would ship to the UK.
