I have loved lizards ever since I was a little kid. They're fascinating, and the beautifully colored ones really make me yearn to keep lizards again. I'm not even sure what the species are out there in the pet trade.
edit: wow, maybe not after reading the article! I see that a fairly sophisticated set up is in order to really keep lizards healthy long term. There needs to be a lot of attention to detail concerning getting the climate and conditions just right... temperature, humidity, different climate zones, light spectrum considerations, etc. I had no idea it was that tedious to do it "right" for these creatures. Also about the varied diet that they need to thrive long term, Crickets and mealworms only (what the pet shops would tell you is sufficient) is probably akin to feeding a bird only seeds and nothing else.
