Why would anyone buy a rack?

[King's Royal Pythons]

I am not affiliated with them at all, but after keeping up with this thread and doing some research, the racks from C Serpents Reptiles are the cheapest per slot rack I've found. They come with heat tape that is in a slot so the tub does not rub on it, and they come with the tubs. Made out of 1/2 inch pvc. I think the cost for an 18 slot rack (3 wide, 6 tall shoebox tubs) with heat, tubs, and shipping was $265.
I think I've built my last rack.

That should have been "C Serpents Reptiles and Racks" (don't know what happened)
