not sure what the good stainless refered to above is, 316 is good, but isnt shiny and pretty like the stuff they make kitchens out of!
316 refers to the nickel and chromium content from memory 304 grade is cheaper quality but more common than 316. The finish is down to polishing mill finish just grey looking satin finish has agrain to it then mirror finish or ba finish all the finishes can be obtained with nearly all grades of stainless it is just polishing processes
