My large cages just sit on a folding table I got at Lowes. It has a grey plastic table top and black metal legs. It is not the best looking table in the world, and it wouldn't look great in a dining room, but in my snake room it looks just fine. Im need to go get another for the new cage I ordered.
Some of my other cages are on purpose built stands but they are not large enough for a 48 inch cage.
