Hi, I'm new to this site and it looks really useful so I was wondering if someone could help me.

I have a couple of digital cameras which I really enjoy using, but on both of them the shutter speed isn't adjustable. I want to get into long exposure photography, but I need a new camera to be able to do this.

I am a student and a beginner at long exposures, so I would prefer a camera that isn't too expensive at the moment while I am only just starting out. If anyone has any recommendations for decent, cheapish cameras for taking good long exposure shots then that would be really helpful! Thanks very much in advance!
