For those of you who are like me and hate having to scroll down, I thought I'd bring this forward from a thread I responded to way below. This method has worked well for me and some of you may find it useful.... 
Since it's quite warm here in Los Angeles (sorry, don't know where the rest of you are at), I went to the local Smart & Final store (they carry catering supplies) and purchased dinner boxes like the ones you would find at take-out places. The largest is 10" x 8" x 3" (they stack easily). I just punched some holes in them using a hole puncher and I've got an instant hatchling rack! I include (2) 8-oz short food containers inside. One to hold water and the second is turned upside down with a hole cut out and used as a hide. Quite surprisingly, it holds heat and with the 'waterbowl' inside, there's instant humidity. One package which costs all of $16 contains 20 dinner boxes and they're made by LumiStar.
If hatchlings can be sold at shows or shipped in deli cups, I don't see why they can't be maintained, even briefly in these dinner boxes. I went a bit further and used 3 x 5 labels so that I can write a description of each (male/female, color & markings) as well as the dates that they've fed and what they ate. This worked for me with last year's batch and it's a nice presentation when you're selling off the hatchlings you don't need for your colony.
I'm also looking at getting Sterilite boxes, I just have to find the space for them and figure out how to heat them in winter. I also want them to look somewhat like display cages because I'm not into that 'plastic milk crate' look. My friend and I built 2 melamine cages of our own from scratch. We took a look at what they had on Showcasecages.com and made our own version for half the price. I'm currently designing a plain cabinet to house my computer and peripherals. I'm designing a double cage (side-to-side measuring 14"H x 48"W x 16"D) to sit on top of that (my monitor, speakers and printer will be above, like a normal looking computer desk). I'm pretty much making most of my furniture into useable furniture/cages. My Ikea bookshelves that were converted into cabinets are next. I'm thinking about using only the bottom halves as cabinet space where the top portions will be turned into cages. I know Sterilite boxes are more practical but I want to be able to see all of my snakes in a 'display' situation. My headboard is currently a 60 gal aquarium housing my Discus and plant collection. If I can find someone who'll take good care of them, I may sell it and make a new headboard with stacked cages just to house my snakes (stacking's the only way to go when you live in a small apartment). 
If anyone has stacked Sterilite boxes and figured out a way to make them look more like real furniture and heated, please let me know or show me a pic. I'll be taking pics this weekend so you guys will see the dinner boxes that I'm talking about here.
