I'll add my vote for the seven jib. It's tough, sets up fast and it does the job. We use the sevenjib on doug's dolly and it works quite well for fast paced music videos. I will say though, that the 7jib logo sticker ripped off after we gaffed some cables to it, so if the logo is important to you, you should look for a company that uses tougher stickers.
For that matter, my red logo fell off the front of my camera when it came out of the box. I must have bad luck with adhesives.
doug is great to work with btw.
