I agree on the Google thing.
BidVertiser is another decent PPC Advertiser.
If you notice with Google (before my account got terminated), they where paying out alot towards me, within a week i made $17, which i thought was great, seeing i've never used my AdSence account alot. I used it on and off for 7 months.
but then i got that dreaded email, "Your account has been disabled", and as usual, Google being them wouldn't re-instate my account. I only had $17 dollars, and i was causing "financial problems" for AdWord publishers. Google are starting to collaspe with their strict publishing rules, even if you aren't abusing it.
