Ebays your best bet, you aint gonna get em cheaper than 120 brand new. Just get a used pair off ebay, not like much can go wrong with lights? Bulbs needs replacing thats about it. Got mine off a guy on here for 75 posted, he listed them on ebay
I got a site where they only do morrettes & angels only but they are brand new and £££ but atleast you will get a warranty and if needed they will ship to a local body shop if u require them colour coded or fitting selecred are's of course.
black ones always cost nore as they look smarter so are more desirable, the ones I sold MUFC were chrome originally. I took them apart to replace the LED's as a couple had failed and decided to blacken them too as my punto was black. looked good but then went back to standard so I sold them. Best bet will be to bide your time and watch ebay, use the search tools i.e. newly listed and check daily.
