Zircon WL25 Pro Water Level
Water levels are great. They're cheap (all you need is a piece of tubing), accurate (water finds its own level, duh), and can accomplish things that the most expensive laser levels can't (going around corners). The only drawback is that they require two people; one on one end of the tube and one on the other end of the tube.
We saw the Zircon WL25 in a store today and thought it was worth a mention, if for the only reason that it brings this ancient technology into present day by adding some electronics and in the process removes 50% of the workforce needed for operation.
It looks like what you do is hang the level where you want it and once you're around the corner, the level lets out a noise when the water reaches the pre-established spot.
The reviews at Amazon are actually pretty luke warm, with some complaints about the noise as well as the accuracy of the sensor.
There are two versions available; one with just 25' of tube and the sensor piece, the other is the 'pro' version with the tube, the sensor, easy fill nozzles, and a coupling so you can attach the tube to a length of garden hose.
Basic kit $25 at Amazon.com

You don't need two people!
Use any old container onsite (about a gallon size is perfect) and just over half of however long tubing you need.
Set the container about halfway between the two points, close to the height you're leveling. Go to one end, mark it on your tubing. Go to the other, level away. Done, one person.
Maybe $5? Usually free, with stuff already onsite.
$25-$40 saved, for beer, or an engineering degree. :-)
