Hmm, that's a good one to ask. What is the condition overall? Is the Card door still attached? Scuffed/Scratched? Cracks? I would actually need a pretty good description orpics to even begin to estimate it. Oh, and basically, the door latch hinge inside of the DUO was really dirty, and that is why it wouldn't close all the way. Easy fix, and when I worked at Gamedude, you'd be suprised what problems you get when machines are supposedly "Broken". Example: we used to get Atari Jaguar units constantly that were "Broken" because they wouldn't turn on. We'd pop a cart in and they'd come right to life. It would appear that people would try to test the units without carts in them just to see if they worked. The Jaguar has a failsafe mechanism within that keeps the Jaguar from turning on without a cart inserted. The sad thing is that we actually bought broken machines at salvage for repair parts, you wouldn't believe how many Jaguar units we got that actually worked, very sad.
