Wondering if anyone in here has purchased the new PN-40 yet? I know there are a couple of members here with the PN-20, Parmachenee for one and I think Rick won one. Do you guys like the PN-20 and would you recommend the PN-40 from what experiences you have had with your 1st Delorme GPS? I have had this old Vista since I started caching and it still works great don't get me wrong ( although I have to hit it once in a while to get it going again) lol.... I just think it is getting time to invest in another GPS. What are your opinions? Thanks
