I’ve got one for sale, links in my signature.
I tried polishing the scratches out of one but it leaves you with a shiny strip, you can’t easily get it back to brushed aluminium look. I ended up buying a spare one that was dinged up polishing it out, not liking it going back to my old brushed one and then eventually painting the polished one gloss black. There are photos of the black one in build thread (link also in my signature).
