4.3L 'W' engine linear EGR VALVE

I've determined my EGR needs replacing. Does this thing really cost $250??

I picked up one for my 3.8L supercharged for just under $125... That might not be any help.

Well, I got the correct Delco part; $255. She's back to smoking the tires and idling, so it's all good. I could have saved the money and just cleaned the old one after I looked at it, I guess I'll just clean it and use it later. I'm sure they all get the carbon chunk buildup.
