i can make a tanke 10' by 8' by 6' in about 2 seconds. the vedgies arnt bad around here i can get em cheap or from my gardenWhat are you going to do when the iguana outgrows the tank? And, if you're looking for somethng on limited funds, they are NOT a good choice. They have to be fed a wide variety of fresh veggies and fruit every day. Those grocery bills get expensive.
Breaded dragon is a great idea, as is a BRB. Neither would outgrow the tank and long term care is easier and less expensive.
