WTB cheap loose MVS carts for friends B-day

A friend of mine has just purchased a 4 slot MVS cabinet. So right now he is pretty low on cash, even more so because the monitor just crapped on him. His birthday is next month and i wanted to get him a cart or 2.

So im looking for games that are used/loose/cheap. Just as long as they run and are reliable i dont care about much else.

Just took a quick look through the screenshots page and these names caught my eye or were games that i remember playing that would interest me. Im open to anything though.

Aero fighters (or any other game of this type)
Cyber-Lip
King of monsters
League bowling
Neo Drift out
ninja combat
Over top
Thrash rally
view point
Voltage fighter

No KOF or metal slug.

email or post here.

thanks
