I have 6 blue tounge lizards now. I had a gecko, turtle, some tree frogs, etc, but had to sell and give them away. Also have some yabbies, my biggest one is about 25cm long claw to tail.
Blue tounge lizards and yabbies are cool because you dont need to do much to look after them. The lizards are tame as fuck and are so timid.
Never really was interested in spiders, mostly because I wouldnt pick one up or anything. Those photo's are pretty cool, xgrafcorex
