Laser Level for Bench Regulation

[ed440 at mindspring.com]

Is anyone out there using a laser level for bench regulating?
This afternoon I bought a Gen-Tech Laser Level from Harbor Freight ($14.99)
The laser rotates to send a horizontal or vertical plane of light, very useful.
By setting it on some wood scraps and shimming with cards I could easily align it to first and last sample hammers in a section. It was very convenient for setting hammer line and back checks.  For some pianos it could perhaps also gauge let off and drop.
