What size lizard are you thinking? What sort of set up budget do you have? Do you want a lizard to hold, or one that is just for looking at? Do you have space restrictions? What about life span of the lizard? How much time can you spend on care and feeding?
Some popular lizards are-
Anoles- small fast lizards. Green Anoles will change color- brown when cool, green when warm. Initial set up is fairly cheap, a few can be kept in a 10 gallon tank. They eat crickets and meal worms and maintenece is fairly low. This is mostly a pet just for watching. Some can be handled, but it depends on the individual lizard, and they do tend to move fast. Life span 4+ years
Geckos- several different species.
Crested geckos- set up is easy, expense is low. Can be handled, although some are quite fast. These geckos eat mostly fruit. You can use commercial gecko food, or a variety of fruit baby food, or both. They occasionally take live food. Food must be changed daily. A 10-20(long) gallon tank should be fine. Life span- 15-20 years
Leopard Geckos- tend to be quite handleable. Come in several color mutations. Eat crickets and meal worms. Initial set up is a bit more, but not too expensive. a 20 gallon long tank is the right size. Life span- 15-20 years
Bearded Dragons-
These are rather large lizards. Very handleable, supposed to have personalities and get to know their handlers. Eats a mixture of insects and vegetables, nutrition needs change over their life span so would require a little research. Larger specimens can eat baby mice as well. Fresh food needs to be changed daily. Initial expense will run a few hundred dollars. They need at LEAST a 40 gallon breeder size tank, they grow fast, so buy one from the outset, you'll be upgrading within a year if you don't. Make sure its a 40 gallon breeder- regular 40 gallon or 40gallon long won't cut it. Life span - about 10years
