iPhone Site 9000UV a month

So I have a iPhone related site receiving 9000 UV a month from search engine traffic and its rising!

I use to make $500 to $1000 a month, using a cpa download widget on the site for iPhone content.

I had forgot about this site since I moved cpa network, and have Just rediscovered it with a lot more traffic!

How much is it worth?

Is it worth trying to monetize it with paypal/affiliate products?

What would you do?

Scale it up or flip it, I'm in a similar situation right now also,
I got a site that gets 25k UV a month with $200 profit, but it
has potential to make over $1k a month, I just don't have the time.
