I have a very good buddy who works in a shop in the western part of Westminster, just south of Broomfield. I don't know how familiar you are, but it is basically off of US-36 and 104th.
The place is called stang auto tech. Their site is
http://www.stangautotech.com/ He's the guy at the top left (Brian). I'm not sure how cheap they are, but I know that he'll tell you where a better place to go would be, if they weren't the ones. I don't know that he'd be able to do anything price-wise, but you could mention my name (Travis) if you'd like, for whatever it'd be worth.
