New Headlights

I noticed that I am starting to get condensation in my headlights. I have an 04 silverado and am looking for OEM replacements both headlights and turn signals. They don't have to be actual GM brand, but I want something quality. Any ideas on where I can find some? I've also noticed I have a ton of little hairline cracks in the lenses.

Why not just get some good junkyard pieces?

I've looked at a couple junk yards, and they seem to be a popular item because they were gone. The one set I did find was discolored. I'd rather just just buy new, that way I know they are good.
