Brand new unopened in box. I have one nearly identical setup (pictured) and running but am going with racks moving ahead now. It holds a heat gradient and humidity perfectly.
It has some extra added options.
-3 Black Hinges
-3 Keyed Locks
-Florescent Light
-Under Cage Low Wattage Heat X 1.5
-Thick PVC mounting bracket for a Radiant Heat Panel on the roof installed
I payed $396. Asking $375 OBO.
I also have a Pro Heat 115 Radiant Heat panel (60 watts) that would complete this setup for a ball python. Brand new in box.
I payed $116. Asking $100 OBO.
Pickup in 11228. I could arrange for shipping if necessary.
