Great find. I use a laser measure for the same purpose and I agree it's really useful, but it was more expensive than this one.
To those who are objecting that a fraction of an inch doesn't matter, that's probably true, but getting things reasonably close does and it's a lot easier to do that with a laser measure than with a tape.
