What's everyone choice in unmanaged ethernet switches?

I received a NTRON 308TX-N at work the other day and I really like the OPC server it has so you can monitor each port without having to get a managed switch and it doesn't use a secondary connection like our older one which had a RS232 connection on it to see the live data. It actually resolved a few comms issues we were having as well. Price tag for it is steep though.
