Best place for Banner Advertising

I apologise if this is the wrong place to post, please move to the correct area if it is.

Im looking for a place to banner advertise and that would take porn banners.

Im looking to be able to pay per click on the banner on not per inpression.

I tried adbrite for a none porn banner trying to advertise a cpa offer and ended up spending a crap load on impressions and barely got any clicks.

Any help would be great. cheers

im not sure about banner ads.... but i buy per click text ads here and have been very happy with the results
