Found a guy on CraigsList who builds rat rack- complete with tubs, watering system, feeding bins and all.... including whatever breeder pairs you would like.
I ordered a 6 tub rack and it is being custom built with all new components as listed above. I am getting 6-8 females who are all sitting on babies or pregnant and the males who they have been paired with. He is also including 50 small rats as he is very crowded right now. $230 seemed pretty fair considering the proven breeder pairs and small rats he is including.
This is just a picture of one of his 3 tub racks.
