Bought Donkey Kong Land for the Gameboy it was $4 and bought a working (as in the screen and all the buttons work great)green original Gameboy for $20( going to open it this week end to clean it). It needs a new screen lens so I ordered a glass one on eBay it was $5 with shipping(ships in canada).

Cool Play it Loud Green DMG, one of my favorites. Yellow being the best, followed by Green, Black, Clear, Red. I would like to add White, but don't have one yet. So a like for your Gameboy purchases.
