I got one of these Zircon levels years ago for only $14 at Home Depot.

Now they sell for over $40.
They are advertised as accurate to +/- 2.25 arc minutes.
Probably better than a bubble level.
Combine it with a laser pointer for distance and you have a very versatile leveling system.

You're cheating, Jim 8*) That thing uses some fancy accelerometers to magically magnify the level measurments. No fair.
The other place where a laser level really shines (UGHH!), is in making a straight line, especially in places where a string isn't convenient or will get in the way. The cheap Harbor Freight laser I got has a thingie on the end that turns the laser point into a line. Now, you have to work in near darkness, but you can put the laser out in front of the plane, have a line go through both wing tips, and measure up-thrust at the prop flange and dihedral at each wing root. All with a ruler and all in one shot. Marvelous inventions. Just marvelous.
