Just put these up on ebay last night.
Two Apple 17inch Studio Displays (ADC LCD panel) in very nice condition, shipped in factory boxes.
The slightly rarer item is a CompuCable "PowerReach" KVM.
The KVM is an ADC console (meaning it uses your ADC monitor, along with the usb keyboard/mouse plugged into the monitor) and shares the Keyboard, monitor, and mouse between two computers. The 2nd output is DVI, so you can use it to switch an ADC monitor between two macs (one ADC, one DVI) or a Mac and a PCI (adc Mac, DVI PC). I've been using it for the past week or so at work between a Dual 867mhtz G4 and a Dell Precision, works PERFECTLY.
You could also use it just to connect a PC to your ADC monitor... works fine that way as well with just a single PC connected.

ADV/DVI KVM
I've not sold here in a long time, but have perfect feedback under "armwt" on Ebay, and also under "armwt" at Beerology and Heat.
