I have two Cresties. They are super easy to care for. The only problem is that you generally can never have two males together as they will eventually fight. If you buy your Cresties when they are young, you will have to wait to tell their gender. Males develop a large hemipenal pouch at the base of their tales. I have heard that they are super easy to breed as well, yet have not attempted this. Your tank set up should be taller than it it is long, as they are largely arboreal, although I have one who prefers to stay low on his log.
Feeding is easy. I would agree with the others that straight baby food is not the best. I generally mix it with a supplement (Crested gecko specific). I also give crickets gut loaded and dusted once a week. Heavy misting generally provides the H2O. Be careful with their tail as they will detach, yet DO NOT grow back with Cresties.
