Discussion: Webinar software recommendation?

Our club is thinking about doing a series of webinars. Does anyone have recommendations or experience of decent software?

I've used Citrix's GoToMeeting & GoToWebinar the most, and it's likely to be the platform used for future OUSA webinars. GoToMeeting is equivalent for most purposes and is cheaper.

However, for most club purposes and to anyone on a strict budget, I'd recommend Google+ Hangouts. It can be (slightly) trickier to use, but it's the right cost (free!) and usually works quite well.
