Hi! I am an amateur videographer - underwater, etc. I've been out of the industry for about 5 years, but am hoping to get back to it, and frankly don't know what type of camera is best for my needs! I'll be editing and dumping to DVD and some web. Any advise on choosing between miniDV, internal hard drive, etc? Camera has to be fairly compact (to fit underwater housing) and my budget is somewhat limited. Thanks!
