I was looking up the $400 N2024 in the 10Gb switch thread. I then was looking at the N3024. They're around $800 used on ebay. Just for fun I thought I'd check the 48 port version. I was amazed, $800 or less:
$789 OBO: 48 Port Managed Rack Switch Dell PowerConnect N3048 Used Guaranteed Good | eBay US seller 2 left
and
$800 OBO: Dell N3048 48 Port Layer 3 Gigabit Ethernet Switch | eBay (HK seller and $50 ship)
The next closest is over $1.1k.
