If you need huge, go with the one from Soma, it's definitely not light and not the prettiest, but I have both a black and a silver and my main goal with both was to get bikes that are probably too small to get the bars up near the saddle when I've got a lot of seatpost showing. And by huge, I mean I've probably got a good 6" or so of adapter between the stem and the headset.
Pictures of the VO look pretty. There was one that I saw that looked nice with a couple of spacers on it so that you couldn't really tell that it was an adapter. Don't remember which that one was.
