I dunno, but it seems that similar Amigas with monitors can be had on eBay for less than $130-$150.
I have to drive an hour one way just to meet this guy, so I'd better be sure about what I want. Maybe I can offer him $200 for everything? He might laugh at that until I slide two fresh $100 bills under his nose.
Twist, I'm leaning toward the Amiga 500s myself just for the sake of compatibility. RAM disks work fine for what I need to do.
It won't be easy sneaking three old computers past my wife, considering I've got one Amiga 1000 (taken apart now) on my floor, two TI-99/4As in my closet, and four old PC laptops strewn about the house.
