I have had a good experience with maxbounty. They are a great network.
Ads4Dough is legit and trustworthy. My AM is online all the time and is very helpful.
Motive is one network i personally love to work with its been 2 years since i have been working with Motive and never had any issues on payments.
I really like Fluxads. They've got some really good offers, a lot of exclusives and fairly quick support.
yMultimedia is my number one CPA network. I personally have worked with them and my experience has been good. I was able to get paid via Paypal for my earnings of around $450 and the payment was prompt. When I had a question, I was able to reach my affiliate manager via AIM and she was really helpful and really nice.
Lidango is one of the top CPA networks. They have a multitude of offers, their affiliate managers are knowledgeable in what they do. If you are thinking about joining CPA networks, I'd recommend Lidango.
Neverblueads is one of my favourite CPA Networks. The main difference between NeverBlue and other networks is that you actually get an affiliate manager that cares about your success.
Azoogle has great rep in this industry, I always always get paid on the 15th and have been with them for the last 2 years.
