I purchased this cart from a restaraunt supply store in Houston. It is stainless, sturdy and rolls easily around the pinewood floors of the studio. I can turn the cart to face the client so they can see the 27" monitor, or I can simply roll it to where only I and my shoot assistant can see it.
When I don't use it for tethered shooting, I store my studio strobe modifiers on it. It can also be used as a serving cart for drinks and food when we have events for groups at the studio.
