I do VERY well with CyberAge, and a bit less with Net Verifier. I swapped out all my join form for all my sites from PA (which were mirrors of sites on CyberAge) back to CyberAge.
To me, CyberAge really invests a lot of time and money with their models, and content, I don't see them going away any time soon. I'd be
if they did, because I'd say a good 1/3 of my adult income is from my sites with them.
Mike-mijen, I'd suggest either Net Verifier or CyberAge. Net Verifier pays better, but I convert CyberAge better. So it is a toss-up on which does better.
