What are some good beginner reptiles?

I just checked around for the photos. Leopard gecko looks cool. As the name suggests, their pattern looks like leopard.

Bearded dragon is something I have heard quite a few times when people talk about lizards. It seems to be very common.
It is quite a surprise to hear that pet lizard can be wanting attention. Must be fun to have one.
What do they do in order to get attention?

Now you talk about a lot of more complex needs. Variety of diet, that applies to most pet species, not just reptiles.
Light cycle, uvb, umm those are something new.
It seems to be quite a lot for a beginner to handle without extensive research on the detailed care.
