I'm an artist who creates video installations. I need a camcorder that can run continuously. I am only using it to shoot something and re-project it somewhere else in the exhibit, so I don't need to roll tape. The one I'm using currently (an old Sony DV cam) will time out and turn itself off when the tape isn't rolling after 5 minutes. Can anyone recommend an inexpensive model that where I can turn off the timeout? The only feature I really need is slow shutter speed.
