I haven't had a chance to work with them either, but these days the underlying hardware
to build a 24+ 10/100/1000 device isn't rocket science to begin with. It just comes
down to the features / functionality you want, which taking a look at the datasheets
is pretty vanilla standard.
Warranty-wise, Cisco does the "Limited Lifetime," again I cannot comment as I've never
dealt with these devices before.
