Original Sega Lockon

Hi everyone,

I still have my original Sega Lockon, original box, all electronics working, as well as styrofoam insert. The box does have some wear to it.

I'm looking for insurance purposes, how much would this be approximately worth?

Cheers

p.s. i will try and get some photos up soon

Is this the same thing?

Ebay is usually a good start in the right direction. There seem to be plenty of them, so probably not that much.
