I am on the lookout for good and affordable (preferably free) Webinar software.

The obvious option is GoToWebinar, but the price tag is rather steep - $99 per month.

I have tested two free options, join.me and AnyMeeting, but they are both very slow compared to GoToWebinar.

I have also had a look at the Presentation mode of TeamViewer (I have a licensed version) and it is even faster than GoToWebinar, but it only allows up to 3 concurrent attendees.

Can anyone recommend any other alternatives? My Googling attempts have not yielded anything else worthwhile.
