For the record, it was in reference to this one: http://www.ebay.com/itm/Apple-IIGS-A2S6000-Computer-Workstation-Console-Only-/131533481363

I offered the seller (after the auction ended) $22 + $18 shipping, which was even a bit more than I wanted to spend [but I have lots of idle disk drives and keyboards/mice etc. and the color composite monitor].  He relisted for $52 and then discounted it to $41; it appears to have just sold for $39.50.  Doesn't have a memory expansion card though.
