Best place to get a color-matched topper shell?

I have a Pyrite Mica and I'm considering getting a topper for the bed so I can "camp" without needing a tent. Where do you guys suggest I look for a good color match? Thanks!

 

You can order them directly from the dealers. i.e. leer, ARE, etc. If you are looking for used one, they are pretty elusive to find one locally. I found my color matched on craigslist and it was the only one I've seen in years. So bought it right away even though it needed a new back window

 

I'm considering a topper too! Just today thought of this idea for finding a used one. Go to cars.com, and search used and filter to your color, look for ones with a topper and contact them to see if they would sell it separate from the truck. I have the Spruce Mica, forget finding a used one, but found a couple that people are willing to separate in just a few minutes that way!
