I don't want to ship, so hopefully you're local or willing to drive:

10-tier vision rack - practically new (holds 32 qt sterilite tubs, big enough for most adult balls) Comes with tubs and heat cable: Asking $325 (Costs over 500 to have new one shipped and to buy tubs for it).

8-tier RBI juvie rack (great for youngsters. made of expanded PVC, comes with iris tubs and heat tape - these are the best racks for the money!) Asking $175

HUGE melamine rack. Big ugly beast, but holds over 15 snakes. Comes with tubs and flexwatt. Requires disassembly. Yours for 75 bucks.

Ferret Nation - 2 story ferret cage on wheels. Asking $175

Rat rack - Awesome, custom built rat breeding rack. Comes with tubs and has a watering system installed - no more filling all those individual bottles! Asking $100. This system is very convenient.

Lab-style rat/mouse cages (lucite bases with metal tops) Asking $7 ea. Discounts for multiples (I have up to 25 big and 5 small).

Home-built incubator - this thing is a beast. It hasn't been tried yet, but it's made of plywood, 2x4s, and is lined with reflectix. It also has some pretty cool lights in it. Yours for $75. (i'll throw in some heat tape)
