ImLive.com is one of the oldest player in the webcam sex business. This website usually has around 600+ live models at any given time and a good thing is that most of them is fairly cheap, compared to other cam sites.
On your private shows you get first 20 seconds for free, so if you don't like something in there, you can leave and you won't get charged. Sure it's not a lot of time, but still better than nothing. They also have happy hours, when some of the models provide shows for a reduced price.
ImLive makes a lot of users very happy and not only that, they also make their models happy as well, that's why ImLive is on of the "happiest cam places" on the Internet, for users and models.
Highly recommended, go and check it out by yourself!
