I will not order from Unicomp, thanks to you and you post.
Unicomp is an exceptionally excellent company in the customer service department, and the
"Spacebar not included" bit is plainly posted and visible in many (but perhaps not all) places. Do I wish that they would offer old-school sized space bars in bright white? Yes. I would buy 1 for sure, and possibly 2.
They are a niche provider, in a tight place in a small market, and they deserve respect and support for what they do.
And if they revived the SSK, they would sell somewhere between 100 and 1000 of them in the first month, saturating the market, and then the orders would trickle in a few per month for half a decade, at best. Worth it? Who knows?
PS - the red/green/blue legend sets are awesome - buy them in pearl/pebble and don't worry about the sapcebar!
