Digital Photography School have finished their series on tripods and monopods by listing some alternative products and ideas. I have three tripods, two are bulky, one of those is fairly heavy and the other is a small 6 inch high one that fits in my camera bag. The small one gets the most use as the other two are either at home or in the car when I need more stability.
He forgot one alternative, the string tripod which is assembled from a length of string and a bolt small enough to fit the tripod mount socket on a camera. It’s also called a chain tripod. Simply screw the bolt into your camera, stand on the other end of the string and hold the camera to your eye making sure the string is taut. Sources say you’ll get 2 stops extra or shoot at 1/8 sec which is quite impressive. What’s more, it’s a lot more portable than any other tripod or monopod. I really must do some testing and see just how well it works.
The rest of the DPS tripod series is worth a read too:
