Is anyone using this? I have been looking into it as i really want a 360 and to see it in pretty much all its glory... But at the mo cant afford a HDTV... So i guess i can just buy a 360 with the VGA Cable and plug it into my 21" CRT (Has 2 monitor inputs i can switch between) and i will get all the high res/def goodness? Is anyone else using the same setup?
