I'd go for the Legend Cx. I personally don;t have any experience with that unit, but I do have the Vista Cx, and enjoy it very much so. The expandable memory is great, and so is the reception. As for the barometer, it is a fun thing to have. Not completely necessary, I admit but fun to look at elevation plots. AS for the electronic compass, it wotks well, but it does need tobe calibrated. But I'm just a gadget-head. I like tech-toys.
