I have been using Black Label for a while now.

For banner displays it roughly seems to work out at $0.01 for everything 2000 impressions - although you can have multiple ads on the same page, so one unique gives you 5 impressions etc.

The price you make per click seems fairly variable, I am sure there is a formula somewhere for working it out, but suffice to say it isn't huge.
