MPLS/MEF Switches and NIDs

Second vote for the Nokia 7200 line, their price points are hard to beat.
The 7250 was originally designed (per the Nokia reps I've talked to) to be
a data center switch, but I've seen more than one MSO deploy them in the
field to great effect. They also make fantastic satellite boxes for their
7750 chassis. The 7210 is definitely older, but is a fantastic little MPLS
PE router.

SRoS is also easy to pickup, considering it was written by ex-Juniper and
Cisco employees (TiMetra/TiMos if I recall correctly?)
