Identify a portable metal stand for 4' x 4' table-tops

I need to identify a portable stand for 4' x 4' table tops made from thick plyboard.

The low standard table height from floor to surface is said to be 28" according to this guide.

This option could work, even at 23" I think but is costly at $31.99

Assistance in finding less expensive metal stands like the one pictured, and in the above link, but between 23" and 27" in height is greatly appreciated.
