I attended the Communications and Electronics session at the NSS convention, and saw a cheap version of the Disto.
Sears (Craftsman) had a version of the Disto laser measuring device. They are being surplussed on eBay for around $50.
Go to eBay, and search for:
Craftsman AccuTrac Laser Measuring Tool 48298
Don't get tricked into getting the one below, it isn't nearly as good. Note the different part number.
