It was the A600, at least until very recently. I remember in the early days of my eBay selling (1997ish, despite eBay saying I registered in 1998), I would have a hard time getting anything for a new in the box A600. My friend's brick & mortar Amiga shop couldn't move A600s at all. It was a terribly underpowered Amiga when it came out and showed the stupidity on parade at Commodore.
That said, nowadays NTSC Amiga 600s are a hot commodity. So I guess it depends on what era you mean. Nowadays? Amiga 2000s are like kryptonite. Earlier this year I auctioned a new boxed Amiga 2000 and got ~$150. I felt like I got kicked smack in the scrotum. :eek:
