Anyone have any first hand opinions on which is the better quality laser level, topcon or cst? Im looking at the rl-h3c or cst lm800, .probably couldnt go wrong with either, but figured Id get some opinions since I have no experience with lasers. Ive been using transits but am hoping the laser will be more efficient. Main purposes for use are lawn renovations, drainage, and hardscapes. Thanks for any insight!
