I recently upgraded to an SLR with video which I think is the greatest thing ever! However the traditional techniques embedded in me to hold my camera don't work with video. It's way to shaky but there are solutions out there but they aren't cheap. I chose to do more of a gun style just for the ease of creating and I am very happy with the end result. Also the cheap versions you would buy don't have focus and shutter buttons in the handle.
I started out with 3/4" PVC from Home Depot. It is super cheap and easy to work with. I bought two small sections for 1.15 or so each then 3 elbows and 1 T. I purchased 2 buttons from radioshack for a few bucks and I had the phone headset laying around. *I had an adapter from 3.5" to 2.5" from a gaming head set you don't need to do this step if you already have the smaller 2.5" and you want to just run that cable out*. You'll need some random wire from the old junk drawer and some solder/tape.
