I would HIGHLY recommend buying a US captive bred frilled dragon if you are nervous and want one as easy to care for as possible. Imports can have problems with hydration, parasites, stress, etc... not all the time, but more likely than with captive bred specimins. The trick is that many dealers advertise farmed (imported) frillies as "captive bred". I would go straight to a breeder if possible or ask the dealer who bred the animal and check it out. Check with KWE (advertises in the back of reptiles magazine or email me for his info)--he is the only breeder that I know of that has had babies recently. If anyone knows any other breeders that has any, let me know.
Here is a care sheet (follow the link).
