i got all 3 gd120s, the green with the positive display was an instant winner, never really liked the red, grey was a close second but i was thinking of getting the grey in the gdx but after getting them, the grey really caught my eye along with the RED! its really not as bright or in your face as most photos but still gets plenty of sideways glances. the green turned out to be "plain" in comparison lol
im still thinking about the gdxs but i think thats enough camo to last me awhile!
as for functions, they are what they are due to the models theyre based on. any more functions they wouldve had to use a diff. model (and charged more). i really thought they wouldve dropped a camo rangeman tho, with its popularity and outdoorsy target market.
personally i think theyre fine with what they have.
ps. you forgot the ga's
