If you can pick up any of the units for $250 your in good shape! I purchased the older DeLorme SE (Yellow Model) 6 moths ago for $250 so if you can get the Garmin version for $250 buy it!
I have the yellow old one pre Garmin and it works amazingly well. I agree, the best combo is On X on your phone, Inreach for texting and a spare battery bank, but you will likely only use it for your phone unless you are in longer than 3 days.
I wish i could download onyx maps on them. Anyone guess when that will be available?
