I have an Xterra 70 and have found some great stuff with it. Since I bought it tho, I traded my DFX for the SE and am absolutely loving this thing. I hate to have the 70 just sitting around while I always grab the SE but I know that it would be a great machine to use in case, forbid, my SE goes down. I do use it every now and then for a loaner to someone that I trust will take care of it but it is really to expensive for that in my opinion. What do you guys do with expensive back up detectors and would I be better off trading it for a water machine(I really want one) or selling it for a cheaper backup and loaner. Thanks for the help
