Buying Vintage Keyboards (Fujitsu FKB4700)

[stevenshaw]

I've been trying to read up on seeing if there's anything to look out for in particular when buying a second handed vintage keyboard, since I'm trying to acquire spamt spam spam one through Kijiji/eBay/online marketplace, but there doesn't seem to be much information out there.

Also anyone have experience with the Fujitsu FKB4700? I found one for a decent deal, and I'm wondering if I should pull the trigger. Yes, I do like rubber domes.
