I will fall on the side of the original poster and say that expecting to pay $150 for an Amiga 1200 is not really unreasonable. If he'd offered $50 or even $75 I would have dismissed him.
You won't find this price on Ebay or from a dealer, though. There is *always* a buyer on Ebay who has bottomless pockets and will outbid you. Ebay has made all sorts of obscure hardware easily available, but unfortunately the competition from buyers has really driven up prices.
However, if you perservere and advertise locally in the "buy and sell" papers, look in thrift stores and go to flea markets and garage sales you *might* find an Amiga for a really good price.
I picked up an Amiga 500 for $2.99 Canadian once at a Goodwill. Bought another with sidecar hard-drive for $35. Got an Amiga 1000 and sidecar for about $10. Got an Amiga 2000/030 plus DKB Megachip, tower case & 1084 monitor for $180. Purchased an Amiga 3000 with graphics card & 040 board for $250. I realise I've been fortunate with these finds (knock on wood).
But these types of deals are few and far between. Most of the time they involved lots of searching and hours of driving to pick up the hardware. Anytime I wanted something *right away* I've had to pay through the nose for it.
Sure, lots of Amigas sell for $150+ on Ebay, but remember that LOTS (more?) Amigas get sent to the landfill every day too. If you had some sort of magical machine that could scan your neighbourhood for Amigas put on the curb for the garbage truck, you'd never have to pay for one again!
