lah is prob the best bang for buck, i picked mine up for $1000, 2 years ago,it's paid for it's self twice over now,(theroretically), eg over 2000+ games at $1 a game + i still have the machine to sell at the end of the day, can't loose
for a keeper value wise GNR- only if you like the music (im a huge GNR fan) so will never sell mine
