I stumbled upon this killer DIY HDSLR site. There are tons of cool ways to save dough on some of the gear necessary to shoot video with a DSLR. Here is a little video showing the results from the really inexpensive Cage Rig. I copied this from the Cheesy Cam website. Check him out. Here Is The How To Build Link.
“My goal was to merge a couple of different products and functionality into a very very Cheap DIY DSLR Stabilizer with Cage function. Another goal was to step up my game and make it look a bit more techy and something not so ‘DIY’. I think I did well this time around for approximately $30.00. Actually it can come down much cheaper if I could find a shorter rail and cheaper handlebar grips. Unfortunately I wasn’t shopping for a deal, I had this idea stuck in my head that needed to get out. It’s a bit of a rush job, but I really wanted to share it with the community. I’ll go back and refine it later with some hotshoe adapters and a quick release plate.”
