My two favorite camgirl sites:
MyFreeCams, for the social experience and the chance to interact with some really nice ladies. Unlike some of the other sites I've visited, MFC has quite a large number of members and quite a few models from Oz. (Also several from the UK, US and Canada.) Unlike some of the other sites, MFC has only female models (but pays them much better and gives them much more control of their on-cam work than than other sites do). Those seeking men or transgendereds should look elsewhere. The two annoyances with MFC are a) stability issues (several
brief crashes per day) and b) an interface that doesn't work terribly well with any browser except Google Chrome (and variants).
LiveJasmin, for a cheaper private show. On average, you're getting what you're paying for compared to other more expensive sites for in terms of lesser vid quality and interface and the
average model being not quite as good. However, there are some real gems there that can be found with a little looking. Their customer service is hard to beat though, and they've been adding a lot of new features and making some real improvements to the interface in recent months. (They recently added an iPhone app!)
I used to use Flirt4Free, but their customer service is virtually nonexistent. They've really gone downhill in the way they treat models and members and most of their best girls are now flocking elsewhere. So I really would recommend against it these days.
