I can't say enough about it the Cinekenetic CineSaddle ($350, www.cinekinetic.com), so I'll try to keep this short. It's simply amazing. In a nutshell, it is a super heavy-duty bean bag made for video/film cameras. It's as simple as that, and yet not.
I can get shots unavailable with any other support system. It is very durable, strong, and well-made. The securing hardware that comes with it is top quality and perfect for mounting on a car or motorcycle or just about anywhere. I've used it on tree stumps, balcony rails, chair backs, a niche in a stand of bamboo, and more.
There are pockets to store batteries, tape, even a Coke, and my beef jerky! The fill in the bag is easy to work with, you can mold the bag to just about anything. Don't throw your other gear away just yet, but I will tell you that I haven't used my tripod in almost a month.
Add this little puppy to your arsenal and you'll be blown away with some of the creative shots it will allow you to get.
