http://www.amazon.com/DeLorme-Earthmate-PN-30-Realtree-Handheld/dp/B002CM3FF6I bought new at Bass Pro Shops about 2yrs ago and it works perfectly to this day.
Comes with topo maps of the whole US and you can download super detailed maps "Google earth style" aerial pics that show tree lines, feilds, clearings...etc. Zooms in extremely well too. Very easy to use and upload to the computer so you can make precise measurements...etc. Very nice unit that is extremely user friendly. Rubber buttons, no scratches...etc- all discs included as well as a 2gb memory card.
Sell for $150 shipped. I paid over $250 with tax IIRC. This unit has been superceeded with the PN-60.
I do not take paypal, prefer USPS money order. I can provide references on this forum.
