I had a $2.0X click the other week, then shortly after I had a click to the same site worth $0.0X. I guess it depends on the adwords user, if they bid stupid and you happen to get them - you can expect a higher click price. If you are in a niche where the people know what they are doing and the competition isn't that high - I am guessing the cost will be lower. Saying this I don't build my sites based on the price of the adsense click, I just try to get decent amounts of traffic and then the money will follow Richard
