I have been looking for a used Equinox 600 for a little while and have found a couple I am considering. One has 2 years of warranty left and is completely stock and the other has a carbon fiber shaft and an extra arm cuff but has no warranty left. They are similar in price. I tend to be pretty easy on my machines and have never had a warranty issue on anything but my main concern is with water. I may occasionally take it to the lake and hunt the beaches. I know it's waterproof but I have heard of water issues with them and a warranty would cover that. I guess my question is, what would you do???
