I buy my racks from animal plastics, yes the lead time is often around 8 weeks but they have GREAT customer service, so if you plan things the lead time is not an issue. I have their economy line 6 quarts and V18 hatching racks, and also 32 quarts racks a for my males.

I also buy racks (with V70 tubs for my females) from Chris @ C-serpents, grew racks also, taste lead time and great customer service.
