I think when you are paying OUT, it's important to think about your payees. Are your payees wanting to use something else? For these small amounts, they may want paypal and that could be one of the reasons they use you.

I have an affiliate relationship setup with one company - and make about $50 a month or so - they pay via paypal and that is perfect. I am not sure I would want to bother with it if they required me to setup a new account with some other program.
