Does anyone know where I can sell a Cisco catalyst switch? (I have 3 almost brand new 4948s.)?

I have 3 CISCO 4948 - WS- 10GE catalyst switches that are almost brand new, but I have no idea how to sell them. I am selling them on behalf of a company that has recently become bankrupt. I know how much they are worth, but I have no idea who would want to buy them.
