Alternate to Google, Microsoft, Yahoo PPC Programs…

I have been using Google AdWords and lately have been very unhappy with the results. In the past I have also experimented with Microsoft and Yahoo, and I am now looking for an alternative to all 3.
I recently encountered GoClick.com but heard from this forum after a Google search that it was all "bot traffic".
Can someone recommend an alternate PPC site which is cheap to start and can get me 50 clicks a day!
Thanks!!
