[Wanted] Tank/Cage/Enclosure for Adult Tegu

Greetings! I am looking to purchase a reptile enclosure to rescue a Tegu. Any enclosure built for a snake (especially boa, reticulated pythons, anacondas), Lizard (I don't need the height of an adult Iguana cage, the Tegu is terrestrial), or anything in between. I am trying to avoid an aquarium at all costs because maintaining the humidity levels I'll need will be difficult.

As for the dimensions, the ideal would be a 5x3x3, 6x3x3, 7x3x3, or 8x3x3. If the price is right. Built in heat, lights, and locks/bolts would be greatly appreciated but not necessary. I am trying to stay in the $150 to $200 range but will pay for quality.

Thanks in advance for your time, I look forward to the responses!
