What type of affiliate system do you like?

Hi guys,

I am in the process of setting up a new business and have a question for you affiliate marketeers.
I will be offering a 50% commission per sale on a tangible product. My question is what system would you guys be most comfortable with as affiliate marketeers? What system do you trust the most and have the most experience using. Paypal intergrated with paydotcom? Or something totally different. I want to use a system which is trusted and understood by the majority of affiliate marketeers. 2checkout also looks good to me but what you affiliate marketeers like is most important.

Thanks!
