Check out a newer Lowe's hardware store. Some of the older ones don't have furniture. I was able to pick up a 4 shelf, metal rack. They come in chrome, black, or white I think was the thrid choice. The model I picked up is 36" wide x 14" deep x 54" high. The bottom of each of the four supports have adjustable feet to level. Each shelf is rated at 350 lbs. Price was $54... no sale price. They also had taller as well as wider.

above is a link, if you click on larger view you can zoom in and out to see the model I picked up. For stability, I used rubber gaskets on either side of several washers with a long screw through it into a wall anchor on the top shelf in two locations to secure it to the wall. Incredibly sturdy and not going anywhere.
