yeah as far as Ive seen,most chameleon pros keep them in screen enclosures,mine was,you just mist the cage.I havnt studied all the types though so some may need more humidity than others.Well Im sure of it,just not which ones.I dont think the op is wanting the price tag though.Unforunatly,most dry climate herps are ground dwellers.You would want more floor space,you might want to keep that for some type of insects or such and since you really want a cool lizard just buy a cheap 20 long tank and use your skills to build a screen top for it.Then you can get what you really want.What about some fence lizards,heat,some rocks and a branch.Im sure some stay small,any other cali guys know more about them?Help this kid out.
