Well there are many kind of gecko's you can look into but not many are as tame as a leo.. There are cresties which have surprisingly good temperments and are pretty cool

If you want to get away from gecko's you could always try a beardie

but these require a bit more attention, time and are more expensive than leo's (more food and UV lights and much bigger vivs) this can be made a bit cheaper by getting a rankins instead as these are smaller than inland beardies so obviously need a smaller tank. A 3ft by 1ft will a suffice for a rankins

Hope that helps a bit
