My Review
I use Adbrite on a number of my own sites and they pay on time. I notice on some sites with the inline ads they seem to slow down the pages loading speed other then that it is really cool how they take words and make them clickable for money. Also it would be nice to make a little more per click 
but I guess that depends on the sites and niche.
