8730w is a good candidate for refurb/used.
Myself - macbook 17" - beautiful screen - pretty cheap. it had a dent and apple replaced the logic board, screen (glossy to matte), upper case, lower case - gratis. 2.66 17" 8gb 320gb 7200rpm - i think it was $1100 used with 1.5 years applecare remaining.
you might say its expensive for used. but it had a warranty, and after the dent removal (seriously i think they took a refurb and swapped my drive over) - awesome-o deal. I usually just RDP in to windows machines so screen and key/trackpad over anything. the battery is not new but man it lasts like 6-7 hours at 50% brightness.
My 8730w is darker at 100% brightness no light sensor - than the macbook @ 50% brightness (no ambient) - how odd is that. i've had the 8730w screen replaced once already.
