I've not kept lizards for a very long time as I only had a pair of sand skinks when I was little. Want to keep one again someday but I cannot pin down any one that really jumps out as a "Yes I want THAT one!" choice at this point. Ranges from anything to a leopard gecko to an ackie monitor (going from least to most ambitious). A jeweled lacerta would be another "unusual" choice, and uromastyx sound appealing for their fully vegetarian habits so I wouldn't have to deal with raising or buying insects perpetually.
