Cisco Catalyst (WS-C2975GS-48PS-L) 48-Ports External Switch Managed stackable

[Ryansta]

Hey guys
We have 2 of these switches that have been replaced.
Any idea where to sell them and what they should sell for?
I had a look at eBay, they are still quite pricey. These are USED with no warranty. 100% working...

Any advice please

Thanks
