You only buy from professional breeders but you don't want to invest in a hatchling rack? How about the sock drawer? Got an incubator yet? Toaster oven?
Sorry. Poor attempt at humor. You can easily make a hatchling rack and use 12" heat tape for back heat with two tubs on each shelf. Costco sells Iris shoebox tubs in bulk packages and they're cheap. I made a hatchling rack out of two $12 shelf units at K-Mart. I had one built for me with 26 tubs which I like a lot better. Check Craigslist for a used one.
