AdBrite or Clicksor?

Please help me to choose which one to use. If you can tell me the reason that you vote for each company, it would help me a lot!

I use AdBrite at my site but i see many people claiming that clicksor is better. I also see people saying that clicksor slows down a site. What is your opinion?

Clicksor is a scum.

At least they were before one year, as they cheated on the results.

So you think AdBrite is better... not even think to change to clicksor, right?
Except google adsense because i am banned and yahoo publisher network because they answer after a few months, what other cpc companys do you think are good?

I like kontera, but they are having much lower prices than anyone else.

We do you like kontera if they are having much lower prices than anyone else? They must be reliable, right?
Finaly, according your experience, what ad company you would suggest someone for a portal with a forum? (with good pay rates, reliable...)

Kontera has very good ctrs (much better than adbrite) and it is good for forums too.

But in general forums as they are not sites with good monetization possibillities, I guess monetization is something that you do after reaching 400 - 500 visitors per day.

Well, as i saw in their site, they have contexual ads... Can i use contexual ads and text ads together? Is this against AdBrite or Kontera's TOS? I searched at AdBrite but i didn't find anything. What about Kontera?

No problem at all.

no idea . I havent used any of them yet.
