Where to buy a Lizard (Vanc.)

[plutoniumJoe]

My son has been showing us that he is becoming more responsible and would like a lizard. We are still trying to decide on the type, I vote for Leopard Gecko but he is a light sleeper and it's nocturnal behavior might not mesh. We bought a tall 25gal tank at PetCetetera sale. Where might be the best place to buy the actual lizard. I know PetSmart has them but I would hesitate to buy a fish there, should I be as concerned with a lizard?

Thanks for any input.

Joe.
