That was the question I had to ask myself a few weeks ago. For some reason, I've got a bug to take/make some in-car videos. After doing a bunch of research on clamps/mounts, I came across the speedmount clamp
and thought my problems were solved. Then I started thinking that $130 or whatever is alot of cash for a pretty simple looking device. So, after a trip to Home Depot and a local camera shop, I now have my very own pseudo-speedmount clamp for a fraction of the price! Grand total was around $34!
