I assumed brushed finish wouldn't show fingerprints as fast, and thus wouldn't need quite as much cleaning/polishing as shiny-finish.
Lodge brand cast iron is pretty cheap: they're like $5-20 on Amazon.
If I had a kitchen here, I'd probably mail order, but even parcel post rates are expensive for a 9 pound skillet. Heh. (but probably not that expensive really). $17 for military parcel post. $5.15 if it were a book and sent mediamail rate :) $40 for airmail to uae, $30 for surface.
