I have a monstrous cage for sale. It's made out of high quality 3/4 oak. The top and bottom are made out of particle board with oak paneling.
WILL TAKE FIRST OFFER! HAS TO BE GONE BY END OF APRIL!
I have heat lamps and an incubator I will throw in for free to! And other extra reptile related supplies that I don't need anymore.
I housed kimberly rock monitors in it before. It's something like 6 x 4.5 x 4.5 ft. It's painted with spar urathane (Bar table clear coat) on the inside so it will never mold. I tiled the entire floor and up another 12 inches on the sides for added protection against moisture. Lighting is all hooked up. I've dumped over 600 into it from just materials! Huge front window!! It sits on wheels so you can roll it easily. A cage this size would easily cost over 1000 to have someone build.
It would work great for anything large. Like I said I had 3 adult rock monitors in here. I have easily over $100 in rocks that come with it, along with tons of drift wood.
