shinglebacks. I've never kept either, but Shinglebacks are very very high on my list of reptiles I need. Also known as the ""Will seriously consider eating nothing but 2 minute noodles for as long as it takes to afford these" list.
On second thoughts, I don't see shingles up for sale very often, so you should definitely get a bluey. (Then I can snap up the Shinglebacks if they're available!!) MUAHAHAHA!!!
Personally I would take a bluey,though theres not much difference in basic care.shingles are more tricky to handle,and I'm not talking about the bitey end
