I will be quick, I know your surfing is important.
My Favorite Exchange of them all (and one I get good results from! and lots of bonuses.)

Over 170,000 members !!
Tezak Traffic Power
Hits Booster Pro.
High Hits.
Quarter Back Clicks - A new one on the scene I thought I would check out, seems ok so far.
Top Tier Traffic - NOT RECOMMENDED !! . 27,500+ members but.... they allow multiple windows for surf, so you may build up your credits, but who is going to see your site??????
Many thanks for your time
Mick !
