I purchased this small business class managed Cisco ethernet switch from goodwill for $29 USD. https://meraki.cisco.com/lib/pdf/meraki_datasheet_ms220_compact.pdf
A total crapshoot on this one; I had no idea if it would even work. This thing is brilliant, I am really happy with it and makes me want to get more of these things. So many features and remote management. Real profesh setup if you ask me.
