UPDATE: Check out my hands-on review of the DeLorme PN-40.
Tiger GPS has the DeLorme PN-40 in stock for $349.95. That's $10 more than Amazon, but hey, Tiger GPS actually has it. Here's the link...
DeLorme Earthmate PN-40 Handheld GPS with Topo 7.0 & 1GB SD Card with free shipping.
Amazon says they will have it tomorrow -- maybe they will, maybe they won't. They often lag on getting new Garmin units into their system by a couple of weeks.
I posted some first impressions of the PN-40 recently. It's looking like the best handheld GPS with aerial photo capability, not to mention a huge additional range of functionality. Stay tuned for a full hands-on review.
