The first thing is what you get free. Well at LiveCamNetwork, like at any good site, members can chat with the babes (with their clothes on) free, but must pay to see nudity. Some chicks will tease you a little in the free chat room, but I didn't see any naughty bits until I paid.
Once you decide to pay, you now have options: You can join the semi-private group nude chat or take the model into V.I.P chat where it is just you and her. The semi-private chat is a little cheaper, but then you have to compete for her attention with other guys in the room. On the other hand, you can drop out of the competition and just be a voyeur sitting back and watching the action. There is even a cheaper spy option that lets you watch, but not chat at all.
The next important thing is the quality of the women and video. The models I saw varied from the cute chick next-door type to the sexy wannabe pornstar. Like the chicks, the video quality varied. There are some babes who have high-def cams, while others had great fluid motion, but average video quality and vice-versa. Most of the babes also have microphones, so you can hear them talk to you while they do their thing. This is even available in the free chat!
Finally, you need to know the amount of content available. In total there are about 180 performers registered at this moment, but how many are on at any given time is pretty random. When I was on there, about seven cams were available, but I was on very early in the morning and I would think that at peak hours it would be even higher.
I liked Live Cam Network. The models are fun and cute and the ones I chatted with were excited and willing to do whatever I asked (and with a big smile on their faces as well). Video quality was inconsistent, but given the free chat option you wont need to waste your money on the poor cams. The price tag for VIP chat is higher than some other sites, but if you find babes and cams you like it's worth it.
