I agree with Michael. Regardless of the licence required and price, these geckos are only with a handful of experienced keepers for a reason.
If you can't afford a class 2 licence, then you definitely won't be able to afford the set up required for a Chameleon Gecko, let alone the gecko itself...
Also, where ever you guys are pulling these prices from ($3-5k per gecko), they do not go for that much at all and you can pick one up for about $1k - however, the waiting list for these gecko's is more of a problem than the cost. There was a trio (adult pair + 1 hatchie) for sale the other week for $3k all up.
