I think we are giving in to DD desire for a pet lizard. We have let it ride for about a year now and she hasn't let up. Her birthday is in a couple of weeks and we are going to get her the lizard. She has been talking about a bearded dragon but I talked with the lady at the pet store and we are thinking that a leopard gecko woud be a better "starter lizard". Does anyone have one? We don't want to bite off more than we can chew.
Both are great starter lizards, and both have different advantages. Leopard geckos are smaller and thus need smaller tanks (a 12-20 gallon is fine for a leopard gecko, where an adult bearded dragon would need a 50+ gallon). Also, speaking as an ex-pet store worker, you do have to take the info you get a pet stores with a grain of salt. Every once in a while you'll get a great person who knows a lot about whatever species you are asking about, but the opposite is also true. Whatever you get, make sure you spend a while researching the care and needs of the reptile. Local reptile clubs or reptile forums are a great place to look!
I think I'll make a quick list of the pros-cpns of each, and you can see which would work for you and your daughter best.
Bearded Dragons:
Size - 16 - 20 inches, some varieties significantly larger (like german giants)
Lifespan - 10 to 20 years, same commitment as a dog.
Diet - Omnivorous, meaning both veggies and insects. Worms or crickets with a calcium/D3 supplement and a variety of dark leafy greens and vegetables.
Temperament - Very friendly and laid back, comfortable with frequent handling and some quite enjoy it! Pretty much complete puppy dogs!
Caging Needs - Babies under 10 inches can be housed in a 20 gallon, but they grow quickly and will need a minimum 50 -75 gallon (wide or long, not tall) cage or tank when full grown. As desert lizards, they need both a proper heat gradient (85F to 95/100F) as well as full spectrum UVB lighting.
Some awesome caresheets for beardies!

Leopard Geckos:
Size - 8 - 10 inches
Lifespan - 8-10 years
Diet - Insects, mostly if not only crickets, dusted with a vitamin/calcium supplement.
Temperament - Usually friendly and ok with short amounts of handling, 5 - 20 mins every once in a while is fine. Avoid handling hatchlings or new arrivals. Give a leo about 1-2 weeks before handling after you get it, as they can become stressed.
Caging Needs - 15-20 gallons is suitable for an adult. 10 is fine if it is a short 'breeder' (aka more floor space). They need a temp gradient as well, (78-88, no lower than 70 at night) but no UVB, as they are nocturnal. As such, they may hid a lot during the day.

All in all, both really are great pets. Both are desert lizards, so while they need good heating (and good thermometers and thermostats, very important!) they don't need you to watch the humidity as much. For both, avoid keeping them on sand or with heat rocks at all costs.
Another great beginner lizard is the crested gecko. Very tame, very cute and very easy to care for. The like room temperature, so heating is not as much an issue, but on the flip side need more humidity. So daily misting is a must. Another plus, though, is that these guys don't need to be fed live insects.

All these reptiles come in a variety of 'morphs' or colour types, but even the normal types are gorgeous. If at all possible, see if you can find a breeder close to you. Often times if you buy directly from a breeder you can get a healthier animal at a much cheaper price, and they would probably be more than happy to give you any advice you need.
Best of luck in choosing the reptile for you, but you really can;t go wrong with any of these guys!
