Anyone using one of these? They are blowing them out......$995 at B&H, as opposed to $3500 originally...just wondered what went wrong with them or if they have been replaced by a new line. They say they are HD compatible but I am wondering if that only applies if you get one of the HD-SDI inout cards at another $1500. Can you just use the component in and still get 720/1080? Any recommendations or experiences helpful.
