Boyd,
I bought the Montana 600 a year-and-a-half ago after consulting with you. Many thanks. Early on I developed a problem with screen-touch calibration and Garmin quickly replaced that unit (new model flaw). It's replacement has worked very well ever since.
The Montana is a rugged system with a long battery life, working well in field and in auto. It is useful in flight too, so you know what terrain you are looking at from 35,000 feet. The screen is just big enough for easy road navigation, yet fits in my pocket or in a dedicated belt pouch. The elevation option seems to be off by as much as ± ten-to-fifteen feet. This may not be a problem in the Rockies, but the error makes a big difference when trying to understand Pine Barrens geologic relationships.
Cheers,
Mark

I would have to say "caveat emptor" if you buy a used 60csx - seems very risky. Assuming that you can verify it really has the SiRF chips, it's a consumer electronics device and has a finite lifespan. If something fails, you will have to send it to Garmin and they will replace it with a model that has MTK chips. In fact, I suspect the time is coming soon when they will just say it isn't repairable and will offer you some other device at a discount as a replacement.
