Those PLS are pretty nice... I may have to have a look see at those.
We went through a bunch of leica's; hilti and various "semi-industrial" (ie the dewalts, bosch, makita's etc) line lasers before we settled on the dewalt's... Accuracy on most of them is amazing - I have a bit of an issue with the dewalts line width (nowhere near as fine as the hilti and leica's) but still miles ahead of the good ol water level
I keep eyeballing some of the new survey laser gear - leica rep showed me a new toy that I'm hoping will be available next year, all in one rotating / broadcast / plumb / rangefinder... It was a great tool - was thinking it was broken when we tested... Turns out that shifting number was the buildings wind deflection @ the roof...
Basically you could set the tripod in the middle of the building and it would scan in the whole room into a 3d cad system. Then you could walk around with the remote - and check for square/plumb (all paralax corrected etc). Just scared to see how expensive that bad boy will be...
