I've been looking at the possible constructs in current Pathfinder bestiaries looking for options for a crafter character and I couldn't help but notice that the pricing of the [clockwork soldier](http://www.d20pfsrd.com/bestiary/monster-listings/constructs/clockwork/clockwork-soldier) (Bestiary 3) seems unreasonable.

It's a CR6 construct, but the price is 37,000gp. Even following the [pricing guidelines](http://www.d20pfsrd.com/magic/building-and-modifying-constructs) offered in Ultimate Magic I can't understand the price. Can anyone explain why this construct is so expensive for its abilities?
