Picked this up a few months ago but I'm going back to Cherry. Board is in mint condition. I bought it from the original owner who barely used it. The board has no more than a couple months of light usage. The 23UB is the same with even less use.
Original boxes for both are included and the 87UB comes with the control/caps lock caps to swap.

23UB $80 shipped/paypal'd
Both for $260 shipped/paypal'd
