I'm drooling over Elgato's HDHomeRun. But I'd like to hear real experiences. How is the quality over Wi-Fi? Does the HDHomeRun have to be connected by ethernet, or can it connect to the network wirelessly? And all-in-all, should I get this? Or go with the Hybrid or the 250 Plus? And a sort of related question... how often does Elgato update their products? When is the time they usually update their products? I'm wondering because I don't want to buy the HDHomeRun too close to a possible upcoming update.
