Where do you find "new" sponsors?

[Pookie]

I tend to find them when I visit other tgps/mgps or when I'm reviewing for my tgp. There's also frontendengine.com but i dont know how often thats updated

i usually post on adult boards asking for sponsors in specific niches... works a treat...

I check what other people promote, especially on paid spots. But about 1 year ago I decided to promote only sites that make me horny, my results were never so good. :)
