I just picked up the pn-60 last month and it is a good unit. I got it mainly because of the accuracy and electric compass. The only thing I can say that I did not like is that the process/steps to get around it was confusing, but I got use it. as far as the TOPO maps I use my phone to get me in the area, but used it a few times and the beeps for when to turn scares the wife when she is not expecting it.
