Heres the tanks, they might be too fancy if your looking into more then one or two.. or 3 balls.... but these werent to hard to set up. Worst that could happen is you may get an idea off these.. most people use Rubbermaide tubs and rack systems....those work very well too.
First one is a 20gal short i think the call it.. because its not a tall tank... substrate is cypresmulch, two hides but lots of places to hide. Working on the lid, right now use a CHE and a Heat bulb, and heating pad. Keeps the tank at about 90 on hot side, 74-77 on cool side. Humidity-55-60
Second Was my cousins, we had to 10 gal tanks one on topof the other, small crack and held tightly together (used what we had, with the space she had) One hide, which we added another on the upper shelf, used sheet vinyl for bedding, easy to wippe off and re-use. Heat bulb on top kept tank at 90 on top, and 78 on bottom, also had a UTH on the bottom. humidity- 55
Third tank is my snakes hide away, hes under a T.V. stand we rarely use. Its about equiv to a 30 gall id say.. little shorter but makes up for it in depth. we built it, used Flexwatt tape under the sheet vinyl and a pucklight on top, keeps one side at 90-95 and other side 74-76. stick water bowl two hides.. yada yada.. Humidity-50-60 Oh and my snake was going into shed in the bottom pic, so i have that plastic tub in there for a humid hide, which was about 75-80 in that little spot.
Hope that helps some??
