How about something like this? Looks like it's in my price-range. If I really cheap out on the computer and an external hard drive comes as cheap as Justin says, I might actually be able to get it all at once.
Only thing is, I don't want to make shaky cam/found footage movies. I want it to look like it was shot by someone who knows what they're doing. So do I need to find three experienced camera operators or is there some shortcut? I've seen camera operators use some sort of mobile stand sometimes, do those come cheap at all? Would they need to be selected with a specific camera in mind?
