So far the HP ProCurve 4000m is looking pretty good. A pair of
half-populated units (J4121A) is less than the price of a fully
populated one. CDW has them for US$45.72/port. (Due to a HP promotion
currently running.) VLAN (802.1q), IGMP, monitor port, SNMP, stackable,
CoS stuff, &c. GbE ports (SX, LX, and 1000Base-T) are available for it.
Some limitations, e.g., 8 MAC's per port in secure mode.
