Beardie definately, but I prefer the Eastern's personally.
You can house it in a 2ft aquarium for a few months, with just a hot basking site at one end (up around 35-40 degrees). Make sure he has REGULAR access to direct, unfiltered sunlight (make sure any outdoor enclosure has a roof if getting a juvenile - it may be eaten otherwise). Regular exposure to sun at least every 2nd day.
UV lights in the tank are recommended by most people, but I think why bother if you can get them outside. The UV globes do nothing compared to sunlight. 30 mins a day is sufficient and UV exposure is totally essential to your lizards good health.
Plus, beardies have an amazing array of displays and behaviours, they are awesome to watch.
