Looking to purchase a sony dsr 250 dv/dvcam video camera. The camera is used and about three years old. I was hoping if anyone on this site had used one or better yet owns one. The hour meter shows 14x 10 hours on the operation7 x 10 hours on the drum 3 x 10 hours on the tape run and 6 x 10 hours on threading. I really dont no what these meen. If anyone could explain them to me or tell me if this camera has low hours.
