im using ero-advertising banners and using my own ads as fillers too, also tried using choker popunder for awhile but got sick of the tubesites showing up, i mean its fine if they pop up real ads, but to pop a tube site on my picture tgp is Directly Competing with my site
im also using juicy ads but their filler ads pay much lower then ero-advertising, also their system for using your own ads is not so advanced, you can only use images and cannot rotate between several ads. compared to ero-advertising where you can use iframes and set individual weights for each ad.
imo its only worth using juicy for selling directly to ad buyers because they have automatic-pricing which ero lacks..im still using juicy for now..but that might change next month when my only ad buyer ends his 1 month spot
tried plugrush for awhile but i seriously doubt they will last as a 'plug seller', just my opinion.
my review
ero-advertising - best filler price, best own ad system, lacking in automatic pricing, has other ad types like popunders, layers
juicy ads - only good for selling direct to ad buyers, filler ad income sucks, 'own ads' system is really basic
plugrush - hardly any paid plugs, min payout $100, combine both and you get the answer
choker popunder - pops up tubes, aggressive raw pops can over-piss surfers but earn u more money, probably suitable for tube site owners
