I don't really handle either species. My leos are all abit skiddish cause i haven't handled them much which i'm starting to to change now. The new girls i just got will be handled alot more than my original group. I find Bell and Bubbles to be so calm that handling is possible where as my group of 5 girls are a bit more difficult. The male leos are out of the question as Bronx bites and Boo....well he'll tolerate it but not for long (i have to take him to a different room cause if he sees the girls he just goes nuts lol). My three cresteds are wonderful to look at.....but they can jump and don't stay put. Its a struggle just moving them from one tank to another to do a cleaning as they are masters of escape LOL.
Now not every gecko is the same...some people i see post pics of them handling their cresteds and leos without trouble and i think its been my lack of handling thats caused my first set of girls to be so intolerant of me. Each gecko has their own personality too. Nala is very calm, so is Abby, but Dot is just a handful. Besides i'm more inclined to sit and watch them for hours interact within their enclosures.
My geckos all know who i am and that i give them the food. Most (except Bronx) will lick my fingers and not freak out when i'm in their tanks.
Now leos do require more equipment than cresteds. Under tank heaters for example. The cresteds like room temps but other than that the care is the same, they all take up a good amount of my time regardless. I would personally start off with a leo, giving it time to settle in, then starting to get it used to you, working up to handling it.
Either way you'll be entering into a wonderful experience. Geckos are great

>>Well we went to this herp world on Saturday. It was most excellent. I have pictures of the sweetest little leopard Gecko in my son's hands. But we weren't ready for him yet. They had about 50-60 different ages/stages/colors of leopard geckos. But the things is the girl showing them to us suggested we go with a crested gecko instead of a leopard. She said they are so much easier to care for blablblablaaaa better personalities blablbalb. She kinda broke my heart. We still haven't decided 100% that we are going to get a gecko, still weighing all the options and doing lots of research. One thing hubby read was that you shouldn't handle leo's very often if at all and I know we will want to at least occasionally. Thoughts please?

>>Also, thank you all so much for your most excellent advise on my other thread!
