The Orange Box = $30 trade in at GS with a 30% extra trade (promo going on) +10% membership means I got $42 bucks for it. I got it at TRU 3:2 sale which means it cost me $40 plus tax. Considering I spent about $1.50 to play portal and learn that I don't like Half Life 2, I still give it a thumbs up, lol.
Interesting that my local GS already had a BUNCH of Orange box used -- like 10 already -- twice as many used Halo 3 and given the number of Halo 3 copies sold, there must be others like me out there that prefer the H3 experience over HL2.
