cj.com is pretty good. They've got a wide selection of advertisers who have various payment types. Some advertisers there offer bonuses and incentives -- especially if you've got the traffic and/or sales.

The linking code is leaner and less complicated than places such as Linkshare.

I think most of the advertisers there work on the basis that your money all gets pooled into one check. So if you're working with 3 or more advertisers you don't have to wait until you get to the magical payout threshold of x amount of dollars for every single advertiser. At least that's the way it works with the ones I'm using.
