[Closed] Finish for aluminium CX frame. Polished? Brushed? Disc Mounts?

What do people think of polished or brushed aluminium? I have polished a CX frame recently, and I think it looks quite simple/neat.

However, I have a couple of frames I want to sell. I can either sell them as they are tatty/paintless (and get bugger all for them), get them sprayed (cost ~£30 and someone may not like the colour, or I can brushed or polish them and leave them uncoated (takes a long time).

Also, would disc mounts be a plus to you? a local fabricator welded an IS mount on the said frame and its a neat job.

Thanks,

Michael
