If you're contemplating Tacx you might check out our software as well then. I think we offer competitive deal and quality of our videos is second to none. We've just opened our own riding network (it is rather primitive for now and for some time it will stay free as we add features). I would not call it strictly racing but basically you are visible on the road and can see others. What you do (ride along, race, etc) is your own choice.

Forgot to add, I am Zwifting as well every once in a while. I even managed to get (my avatar of course) to one of their online videos.
