This upcoming season will be my first season breeding, so I have yet to get my first rack, but I'm with you. AP is a great company, great products, I love the cages, but I plan to build my own rack, or using lids on the tubs and stacking them, as I am only going to have one or two clutches.
However, if I ever get more into breeding, with six or more clutches per year, I think I'd invest in a high quality rack such as an AP or a Boaphile.
