I saw this very interesting motorized, modular camera platform that can be used for both video as well as time-lapse shooting. Check out the company's Kickstarter campaign HERE.
I've also had my eye on a Dynamic Perception rig but they don't offer the panning and tilting head - check them out at http://dynamicperception.com
If you shoot with Canon equipment I highly recommend joining Canon Professional Services (CPS). They have once again performed repairs for me and they are extremely quick and efficient. You can join at the Silver Level at no cost but higher levels of membership also include free cleanings and loaner equipment as well as a chance to evaluate new gear.
