Dream,
That might work in a pinch, but it’s really not designed for production. If you’re rollin’ on the cheaper end, you should take a look at some of these small mountable monitors:

Also another option is a Sony Clamshell, but you’ll have to check the reviews as to whether it’s compatible with Canon Rigs. I use a canon DV and a JVC HD rig and they work fine with it. There might be a conflict with the ‘F’ framerate the canon HD cams use. However, if you’re shooting in 1080i it might work just fine.
