What type of lizard should i get..experienced keeper, but new to lizards?

im looking at purchasing a lizard. im not a rookie when it comes to tanks, lighting, heating, humidity, different animal breeds but i always like other opinions. i currently have a 30gallon gl tank, two t5 ho lights, a flourescent light(which im getting a red bulb for nightime viewing), a lamp that can be used for a CHE or regular bulbs(which i currently have an infrared heat bulb), humidity and temp gauges so most my basics are covered..im somewhat of a plant guru so i decided to add various forms of live cacti and rock to create a vivarium..this isnt a substrate question, ive researched whats harmful and what is not to reptiles soil-wise so please no comments about substrate, im covered as good as im gonna be on that area..now for the question...ive ran my setup to get an idea of how my humidity and temp are during the day/night..my basking side is a temperature of no more than 93 degrees max with my lights and heater on during day. the humidity is usually between 45-65...im not interested in leopard geckos and to be honest i like exotic whenever possible, what would be the best lizard to get for my setup..serious replys only please, out of all my research im still stumped on this issue..
