Does anyone have any experience with these two products? Are there any cons or pros for each? At first glance, they appear almost the same, but the Miglia seems to come with an antennae, while the EyeTv 500 does not (is an antennae absolutely neccessary?). If anyone can give me pointers it would be greatly appreciated. I mostly want it to record High Def to my computer, because I like to make clips of my favorite shows and what-not.
