Delorme PN-30 leak? in GPS technology and devices Posted May 12, 2009 Debbzilla I have a PN-20 and I love it. For as low as $132.00 wallmart you can't beat this unit. I love the paperless caching ability and Delormes after purchase support is the best of any co. I purchased this and a Garmin Venture HC when my old legend started acting up and kept the PN-20 for myself and gave the Garmin to my wife aslo I just upgraded to the new topo 8 release for just the cost of shipping (9.95) they also have a 30 day return policy so if you're on the fence it's risk free. Cladius. NOTE I also purchased the travel kit that eliminates the need of batteries (it does eat them up) and am getting 8 hours or so on a charge of constant use.
