I would built my own, since I'll be building four wooden stacking display cages for my corns this summer, but I don't really have the ability to make the measurements/cuts as precise as needed for a rack. So, my dilemma is: buy materials at 1/2-1/4 the price of a pre-made and screw up the construction OR pay through the nose for shipping of a rack I know will work out well. Choices choices...

Not to mention that money is tighter than a misers pocket right now...
