Best PPC network (lots of advertisers) for a niche website

Here is the deal: I currently use adsense and auctionads on my gallery, but adsense does not pay through paypal and the clicks pay very low.
However, my gallery is for Japanese Rock Bands/Artists, so I would want an ad network that will have plenty of Japan related ads, and pays with paypal because I am not giving out my address.
So what other network out there might be big enough/have enough advertisers to provide me with relevant ads? One of the bigger, more popular adsense competitors please, not small, new sites..
(And no, this is not an opportunity for you to advertise your ad network unless you honestly believe that you have enough Japan related ads to provide me with more than one or two relevant links. So no adtoll or anything like that)
Thank you~
