What's the difference in value between Jap and US MS4?

I'm wanting to trade/part ex my US Slug 4 for the Jap version. Whats the price difference (roughly) between the 2 versions (in the same condition)? Not much I know but how much? I tried ebay completed items and searching the selling forum but I didn't come up with much.
$20?

They are the same price. Look in the neo store and they are both $235 brand new - no difference!!!

That sig is tight, but "homos" may complain. frown

Nothing much really. The US version is $249.00 as was the Jap version but now sold out. You should be able to get an even trade with someone here.
