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
