Try gomeetnow.com. It costs only at $12.95/month, which is next to free and provides guaranteed attendance in meetings through its unique patented technology.
I've only had limited experience with webinars and I'm not certain these actually qualify as a webinar but Google+ offer what are called Hangouts. I have participated in a few of those and they seem to work quite well. Best of all *free* to all participants.
Oh, and if you sign up or have a Google+ account look me up and add me to your circles.
