I have both clickcash and streamate white labels:

I promote streamate off a tab on one of my sites, and my clickcash white label on its own via PPC and ad networks. ClickCash has a bigger learning curve to set up, but converts better for me (hence I can afford to do PPC with it). Streamate has a beautiful interface and ease of use.
