Heres my reviews on the same networks

Adsense - best network you can possibly use, payment same day every mont

CPX - Low CPMs (0.09 average) .. Currently running on NET120 (just got my payment for December today)

infolinks - didn't use them long but they work.

Smowtion - they only count about 1/2 of the impressions you send them and if you have high traffic CPMs drop to 0.06 .. I have yet to get a payment from them

Bidvertiser - I got a glitch in my account with them.. they owed me $600 I sent about 20 emails back and fourth getting a different person replying everytime and ended up only getting a payment of $10 months later..

adbite - WORST ad network there is

clicksor - good if you like giving your visitors malware and various viruses

My additions
------
Xtendmedia(matomymedia) - friendly staff CPM around 0.12 average for organic Google traffic

Harrenmedia - best payrate, slow support, always pay on time (wire,paypal, check)

axill - a nice filler network to make sure you don't put all your eggs in one basket .. pays on time

--------full page ads----------

adf.ly - nothing better then them.. anyone that claims they are lying as I have tried all the competition
