So, is coinopexpress where most of the folks on these forums get their arcade hardware/software, or are there other retailers frequented by our members? I generally steer clear of all Hong Kong-based retailers, but Las Vegas' own Gameland arcade got quite a few problem boards from coinopexpress so I avoid them in particular. If I'm reading their webpage right, they're offering the mobo for $395, the KOFNW cart for $140, and both of them together for $410. The NeoStore is listing both of them together for $525. Over in Akihabara, the latest stocklists from Mak Japan and G-Front are pricing the Japanese versions at 42000 yen ($350-$365) and 47250 yen ($395-$410) for the mobo, and 26250 yen ($218-$228) and 21000 yen ($175-$182) for the KOFNW cart -- or 63000 yen ($525-$548) if you bought the mobo at Mak Japan and the cart at G-Front.
