Ok, that's what I thought. Given standard nice condition used SSKs are going for $250 these days on eBay, I think $500 is quite reasonable for a keyboard that's probably tens if not hundreds of times rarer than standard SSKs. Just wanted to know what other SSK collectors thought though. My guess is that Ripster only thinks it's ugly because he doesn't have one.
Me, I'd take either this model, or Ripster's Lexmark Industrial SSK with the standard keycaps. If I had to choose only one though, I guess I'd go for this with the unusual keycaps, especially being they're blue and really stand out.
I'd say $500 for this (1395682), Ripster's Industrial SSK (41G3600) , or Ripster's Financial SSK (1395217) would all be a good guess for the market price if there was a collector who wanted one. All three seem to be some of the rarest of the SSKs.
