I Need Used Rack Equipment in So. Cal

I hope someone can help me. I am looking for Two (2)Server Racks/Cabinets, standard 19″, minimum 32 inches deep, 38U to 42U in height, vented. I would prefer cabinets with sides, and a front locking door, on wheels. With or without power strips or fans.
I have looked on ebay and a number of other auction sites and found some locally but I couldn’t pick out what I needed from them.
Does anyone know of any Used Rack equipment dealers in the Los Angeles/Orange County/Ventura County area? Please let me know. Thank You Very Much.
