Need help finding affiliate software please

Hi BHW,
I've been considering adding affiliates to some of my products I sell. And I am unfamiliar with this in general.

So I figured I'd ask for some advice. Does anyone know of any reasonably priced self hosting software? Or a hosted soulution with a monthly fee? I want something that is easy to understand and does not require much tech knowledge to install.

If the affiliate signup page could easily be embeded on one of my websites that I want to offer affiliate commisions by just adding a bit of code that be great.

I will happily give out +Rep and Thanks to any good answers.

Best,
~Naz

From what I have seen one of the easiest full featured out of the box options out there is NATS from Too Much Media and it's available for lease.
