I picked one up a couple months ago, it is the 15 qt versa rack. I have it set up with 12 15 qt tubs and 4 32 qt tubs. All running off the the same heat cable (ran it different for the 2 different size tubs of course). Maintains a hot spot of 91-92 and ambient of low/mid 80s. This is in a room that is usually about 71-72 degrees. A few picky eaters are going strong in it among the rest of the animals.
