if i were to get a gecko, would you guys reccomend a baby one or an adult??

i was thinking a baby becuase i would have most of its whole life to tame it and get it used to me and then.......most of the adults are so fiesty and mean (or at least the ones at the pet store are)so i think a babie would be best

as far as handling i think i would be to scared to hanlde something that little unless it was a bigger babie and not those microscopic ones i saw yesterday
