if you see a PTC site with rate bigger than it, I suggest you dont hope too much They will pay you, real advertiser will advertise to PTC site which reachable rate and always check sustainable or not it is. That means you can compare prices to buy package ads and how much they pay standart member.
There are PTC classified based on layout or design site aslike aurora, buxsite, Yourownbux, etc. You have to know that some of PTC Sites have script to create BOT or clicker robot, If you advertise your site at site with BOT, you will get non sense visitor to your site, and sure you will hate this way.
