Z-Systems ADC: worth keeping?

So, I've got a Z-Systems RADC-2. VERY well regarded ADC, but I don't have much of a use for it. Vinyl rips are going to USB via an all-in-one device.

Is it even worth selling? I'd probably stick it on eBay if I do decide to dump it.
Dear Friend,

I've been looking for a  Z-Systems radc-2. Do you still have yours? Would you sell it?
