For your information, I´m just bought a remote control for my video camcorder Sony CX220 very cheap and working great at "Gentles Limited": http://www.gentles.ltd.uk/index.html
They have an incredible variety of gatgets for remote control. It´s worth to have a look.
This is what I got: "gentWIEW-videoLANC" for SONY CX220 (65 pounds). I can ZOOM, shot images and start/stop video recording. The camcorder I use is SONY CX220 (224€, best price/quality I´ve found)
Hope you like
Angel
