Just bought a Ridgid see snake compact (color) with 100' spool, about $4,200. It's not a large monitor but picture is good. It will go through smaller lines but cannot push though too many turns, geat for shorter runs. Also bought a Ridgid navitrack II locator for $2,400. I haven't used it yet but have heard that it works really well from other plumbers, accurate locating and depth measurements.
