Dragonriders of Styx Skull Sled

[tatsunokofan]

The son of a friend of mine is looking for a realistic ballpark value for an unopened Dragonriders of Styx Skull Sled in a good condition box. Beyond a vague awareness that the line existed, I'm not familiar with the Dragonriders of Styx toys or their values, so I figured I'd ask here if anyone has idea what this toy might be going for these days.

Thanks for the help!
