When it comes to high priced BIONICLE items, I am by no means an expert and do not recommend making big purchases like this without some serious research first. If you’ve had your eye on a sealed Cahdok and Gahdok, the only one on Bricklink right now runs about $969.56 before shipping and any VAT/customs fees.

However, one has popped up on ebay for the price of $415.00 USD and about $17.00 for the shipping. BrickEconomy suggests they are currently worth about $448.07 sealed. If that information can be trusted, then this is cheaper after shipping than the current value for the set. They suggest that the price of a used set of Bahrag Twins is worth about 200.00 USD, despite them being in decent supply for 150 USD on bricklink, so I’m not sure how accurate their numbers are.
