Good CPA Network?

I've been thinking about getting into CPA again, just to make a little extra money on the side, and maybe I can grow it nicely in my spare time.
I used to used Adworkmedia, are they still okay? Or are there better ones out there? I figure that CPA isn't all that bad of a gig because, well, new games
and shit will always be coming out, the internet will be there for a long time, so as long as CPA networks don't get outlawed then we're good.

Anyone here do CPA who can help?
