Flirt4free is one of my favorite. Why? Simple!

clear, vivid free chat
quality of models are generally high (yeah.. studio pro, not really amateur)
video quality is high because basically Flirt4free only deals with studios that use high end equipment
regular porn star shows (and if you are Flirt4free's VIP you get to watch the show free)

Here is a sample screen of FlirtforFree's free chat. All I did was:

give them my email address
choose a nickname

and I get to watch the free chat like this one.

Worth-noting:

You may want to consider joining Flirt4free's VIP program for the following reasons:

you will get to watch the porn star shows for free, and we are talking about watching Tera Patrick, Jenna Jameson and many Vivid Girls like Tawny Roberts.
free group chat, you have to pay for 1-on-1 private of course!
10% bonus when you buy time

Flirt4free gay webcam is also available. Guys are categorized to Boys next door, European, Muscular, Swimmer and young boys so it's easy to find the kind of guys you like.

Try out Flirt-for-free and let me know if you have any comments!
