IR sensors are far cheaper, but most have pitiful ranges and they don't like conditions such as direct sunlight.

Yeah, about that...
My Lunabotics team initially was thinking about using a Kinect as a rangefinder/obstacle detector. When someone pointed out that the tent we'd be in was going to be taking some direct IR from the sun, even through the tent, we switched gears and went to a LIDAR unit (matter of fact, I think it was the first one in the first link), as a preliminary test showed that said Kinect wouldn't work well in sunlight. Now, we didn't buy the unit outright, we borrowed it from the school's robotics groups. When it became obvious we weren't going to be able to do full autonomy, the LIDAR didn't make the trip to Florida from South Dakota--something about we didn't want to risk having to come up with the 4-figure price tag for breaking something we weren't using.
