I've actually opened one up, and it's not nearly as simple as it looks. 
Under the plastic cover is a whole mess of very odd looking electronics, 
all sealed under a jelly.  There is a second set of electronics hidden 
underneath that layer, closer to the MAF support.  The whole assembly is 
impossible to disassemble without destroying at least a few of the above 

$360 sounds very steep.  I think I heard $260 or so for one recently. 
Check around some more.  Sounds like you're still being taken for a ride.
