A friend, Silas of uroplatus.net and the late geckoisland.com, has two last I knew. They were expensive as hell too. Like 250$ each I think, and they were merely babies. They're the largest gecko you can get, and an adult would probly need a massive cage. They're freaking huge, have you seen them?

I doubt you'll find any for cheap, you'd need to find a breeder. And ven then I hear they are highly selective about who they sell them to, they're pretty tough to find I've heard.
