I'm looking for another type of lizard, what should I get?

[Izzie]

I have had my two leopard geckos for about 7 years now and I love them but I was thinking about getting another lizard.
I have a spare tank and now I have space to set it up so I should have most of the expenses already paid...

I would like something around the size of a leopard gecko, possibly a bit bigger, relatively easy to look after, easy to handle and quite common so I will be able to find one and be able to research it thoroughly.
I will probably end up with more leopard geckos but I just wondered if there is anything else i could get for variety

Thanks, any answers appreciated
