Your price is way low for a Neo Geo CDZ.
JapanGameStock.com is a decent source for Japanese game systems, and they want $163.96 for a bare one. Add in $27 for a controller and another $27 for the power supply. And, then pay shipping to the US.
They're expensive, even on the Yahoo Japan auctions.
Here's your best option:

The picture is wrong on the auction though.
If you did surface shipping it'd only be $200. Maybe he'd take $140 and $60 for EMS shipping.
