I'm entertaining offers on this. I'll give you a good deal if you can get me a minty complete US copy of Slap Shot for the Sega Master System. I'll take rare European games too (complete). Cash offers welcome too.

Here's the Mark III bundle:

Mark III system, 1 controller and 3 loose games.
The system is missing the expansion port cover, and has no hookups. You can use a SMS AC adapter and RF/ video cable on this system. A US SMS AC adapter doesn't have the exact same voltage as the Mark III (MKIII: 9V 850MA, SMS 9V 1A), but an extra 150 MA shouldn't hurt the system.
The games: Fantasy Zone 2 (top notch shooter, a little damage on the end label), The Story of Mio (you MUST know Japanese to be able to play this game), The Pro Yakyuu pennant race (Baseball game, not released in US, some Japanese, but not enough to prevent playing the game)
You can play SG-1000 carts and cards on this system as well as Mark III games.
