Be careful, though. I picked up a laser level CHEAP on sale, only to discover that although it may be a laser, it's decidedly not level; the laser isn't even close to matching the bubble. I still use it on occassion, but I have to ignore the bubble and sight it along a 4' level.

Also beware that marketing has also caught on to conventional wisdom that "more expensive = better" and thus price is no indication of quality, either.
