I've recently come across a camera mount that I really like. It's a mini ball head that allows 360 degree camera placement, can hold a DSLR and costs under $6. It is solid metal construction and has a 1/4" mounting thread on the bottom. I also like the fact that loosening the screw not only releases the ball, but also the base (to turn). This will give you another level of placement, making it that much more versatile.
This mount solves the tilting camera issue I had with the Frugal Crane, and will replace the plastic mount (which costs $8-12) found on my Table Dolly. I really like it, and I'm sure it will find its way into future builds.
I got mine for $1, after another bidder cancelled on eBay, but I've noticed this model is no longer up for bidding. Still, the "Buy It Now" option for $5.80 (free shipping) is still a smokin' deal. The only downside is that you have to wait two weeks for it to show up as it is coming from China. Very much worth the wait.
