Ayreon - Really cool tech tricks, his videos never cease to amaze me.
Granka/H TIO - I just love his style of filming and skating.
Luft - His tranny skills blow my mind.
Those are the first 3 that come to mind. I'm not going to name which of them is my favourite though as it's very hard to choose between them.
EDIT: SmurfedYah - The things he can do to spice up the look of his videos are great.
