I agree with mainbutter.....emperor scorp is the way to go as far as scorps are concerned...mine is hand tame and spoiled to a point where i have to feed him crickets with tongs lol

spider wise....i'd say hands down, the Chilean rose hair is a great starter.....they are one of the less aggressive species, easily handled, i use mine in the school presentations i do, she's never been the least bit on the shy side & has even learned to give high 5's (yes, very weird, i know)...

hope this helps ya
