Assuming nothing has degraded sitting in the box, then I'd think you could get $175 for it …. bit more, bit less. Figure a new QD MP10 is $300. You'd have to buy a QD driver for $55 to bring it up to spec, so that's down to $245. Even unused, things depreciate sitting in a box for years, so take off $75 and you're at about $175. That's US; converted to CAD that's $23,794.67.
