According to BrickEconomy, a used Thornatus is worth about 90 bucks used. This Thornatus, which the seller warns is missing a few pieces, seems very reasonably priced for a mere $68.50 after shipping. After looking for a minute or two, the only notable missing pieces I could detect were some thornax and zamor ammo and the silver pridak skull that sits overtop one of the wheels.

If you need those tan Thornatus beams for MOCing and don’t need the big wheel, this husk of it’s former self is a mere $34.25 shipped, although the seller specifies “or best offer” so you might be able to knock a few more bucks off.

Lastly, we have a set of 6 used Rahaga for $43.89 shipped, which the seller says is complete. The picture shows the ice rahaga without his spinner, and I would not be able to verify if the remaining spinners are all correct. These are the cheapest on ebay despite averaging more than what BrickEconomy suggests, although the shipping is a real savings. The seller also lists “or best offer” so you might be able to snag them even cheaper.
