i would not be interested in plastics or powder coated. plastic scratches too easily. i made the tabletop for my turntables table out of plexiglass, it is all scratched up not not quiet 2 years later.(wish i would have used plate stainless steel like i used for the legs.) powder coating has a couple of problems also it just seems to look dirty to me most of the time, and it "wears" weird. i know that anodized is not the perfect solution. however anodized has a few micron layer that is much harder than the non-anodized aluminum below it. I would gladly pay extra for filled engraving. not sure what everyone else wants.
