Most people with chrome who want black just scour the chrome with a scotchbrite dish scourer and paint whatever color they fancy. Others have successfully used vinyl wrap too.
The Chrome is real, believe it or not, although it is on a plastic base that has been coated with copper and then chromed.
Or get black polished gel coat fiberglass ones from the UK - 2 eBay sources,
Carbonfiber from Spain - ex China? on ebay as well.
Lots of New Old Stock comes up in different phased out colors too. I got a set of Cardinal Red ones for under US$50 and know of a couple more sets well under a US$100. A Pacific Blue set too.
