I'm in the noodling stage of replacing a rack in my fish room that's been re-purposed too many times over the years. If I can find one of the "heavy duty" units that are built with a 36 X 24 footprint, I will most likely go in that direction rather than wood, even though I can easily build one. The room is very small, cramped and difficult to work in. An "erector set" like these units, would be perfect if they are the right dimension for my needs.
