I had a Commodore 64, paid $200, with no disk drive or Cassette tape. It was said - I typed in programs out of a magazine, couldn't even store anything.
Returned it a week or 2 later and got:
Coleco Adam, $200, 1987 or so. I think they were originally $800 or so but just started dumping them for $200. Not a bad deal - came with a high-speed cassette and daisy wheel printer!
Eventually ditched that and got a full Commodore 64 system.
