Well, I'm told these are worth $300 or so in mint condition. The box does have those flaps missing on one end, but everything else is wrapped/unused, so I imagine 200-250 is fair. I'm no expert on this stuff by any means, but I do know that the unit is quite rare because it's the Canadian version.
*EDIT*
I found this on Ebay today: eBay Auction -- Item Number: 271025286230
Going for $329 with no box and everything is used - he does have Berenstein Bears, though. (shrug)
