Welcome again!

@mediamogul the screen does have trailing issues but the way i viewed the screens on portables was "if its better than the game gear and the atari lynx screens then its good enough for me." I bought my cdx for $90 from toys r us and when i sold it to the same game store i sold the nomads to (game force) they gave me $175 for it. Being in the business though i have gotten so many awesome deals that most people would kill to get.

@GustavoW Welcome, the world of Retropia awaits.
