Best price I can find on Ebay $720ish shipped. If anyone sees any better, LMK. Remember that this is a JP system and will run out of the box in North America. Sometimes they have slightly cheaper listings for Korean units, but they require you to purchase a power transformer to work in the U.S.
Based on that, I'd like to ask for $600 shipped or, at worst $550 shipped and the rest in trade.
The posts above by Rasen and tlp are correct.
To confirm and add a little more info though...
The system is Japanese, but has selectable English language support from the crossbar. As tlp noted, here O is confirm and X is cancel, you know, they way it should be.

Blu-ray region is shared as Rasen noted between the U.S. Korea and Japan, so all of your blu-rays will work without a hitch. And, of course, blus that would be region blocked on a U.S. PS3 will also be blocked on this system.
The system itself is in great condition and is very lightly used as it's mostly for blu-ray viewing. The JP version of FFXIII has absolutely no English support, so I have not included it in the price. If you want it for some reason, please add $15 more. The controller is also not used much as I typically use the blu-ray remote.
I'll be packing it up as safely as possible and ensuring that it makes it there totally functional with EMS insured mail included in the price above.
As stated in the OP (and since I have been asked via PM) yes, I will accept a payment plan, but there are two stipulations.
I would need at least $200 up front and I would need the system paid off before the end of the year.
Of course, I would not be shipping until the system was paid in full, but I believe my feedback speaks for itself and you can feel secure in the fact you will be receiving the system.
