I bought a $1 model M on ebay a few days ago that didn't have a space bar. Naturally, being a geekhacker, I wanted to restore it to its original spacebarred condition. I sent an email to Unicomp asking if I could buy an old space bar, possibly removed during a refurb, and Chuck informed me that they didn't have any used space bars in stock. He instead offered to send me a brand new one for free! They're running an incredible operation, and I'm suddenly wandering why there is no Unicomp in my pile.
