I think it really comes down to what you can afford to spend. For me just starting out i would rather cut costs on the racks and incubators until i can effort to buy nice pre made equipment and spend that extra money i save on the animals. Why spend twice as much on something you can make that's just as good. It just takes more effort if you have the time and equipment i say build your own racks there are so many diy forums on how to do it.
