Amiga was £399 in 1989 in the UK, which is about £1000 in today's money. I expect they were cheaper in the US, but £1000 is fairly reasonable for a computer.
If you weren't a gamer, you probably didn't know Amiga existed.
Some didn't realise that games are pretty taxing on the hardware, but I need to let that go, it's been three decades now. :)
