I have a slightly used (bought june 13th, 2007) sterilite 32 qt sideways rack. you can also put 2 15 qt tubs in one shelf. it is heated with 2 11" stripes of flexwatt down the back. it was made by Casey Hulse at natural spirit reptiles (nsreptiles.com), he calls it a snake shack. it is great condition, i just built a larger rack and i really have no use for it anymore. i would really prefer local pick up (i am in the ypsilanti/ann arbor area), but if you really need it shipped pm me and we'll talk. i can also meet you at the taylor reptile show on august 11th. i can include some tubs just let me know what you need (32 or 15 qt tubs). i am asking $125 for it. and i really recommend using a thermostat with it (johnson control or rancos are fine).
here is a picture....
you can also toss me an email at kevin.k2reptiles@gmail.com
thanks
