On the other hand, something like a Savannah monitor is plenty cheap. The caging and food for one isn't cheap though, and you'll blow through a few hundred dollars in no time at all. It's all in how you look at things.
A Bluetongue may be moderately pricey, but maintaining it is easy and less expensive. The maintenance is the cost you want to look at, not the price of the lizard itself. My suggestions would be a Bluetongue or a Uromastyx.
