I am currently using a hitatchi hdsv01u hd camera on a GLB gimbal and am reasonably happy with results. The only problem its point and shoot with no viewfinder so often its pot luck, unless doing longshot/landscapes. I have recently seen the XiaoMI Yi as a much cheaper alternative to a go pro. It has built in wifi and a Sony 16mp sensor. It gets very good write ups. I was wondering if anyone had tried one out, also would there be a interference problem. At around £50 I seriously thinking of taking a punt. Any thoughts?
