I'm the same way, and try to watch as much as I can. As long as the computer you run the webcast through works well, the game comes through pretty well. I have had hiccups in the games where I've watched it at a delay to avoid buffering, or glitches, and there have been times where my image has appeared to change from HD to Standard. Though it is definitely better that it has been in the past, and some of the issue I have had may be attributed to my internet connection having some issues.
I think the package was well worth the purchase this year, though I believe there are 10 games left in the regular season 8 of which will be on CBS Sports, NBC Sports, of Fox College Sports.
