Juicy is the bomb, if I were you I'd split the traffic and try Juicy,
PlugRush and
SGM for 30-60 days to see what pays the most.
SGM requires that you setup a whitelabel.
In 2011 I sent around 84K hits to SGM and that made me a total of ?2154 (they pay in Euro, you do the math if you want that in $). It takes some work to get setup, but once it's rolling you'll be happy.
