Russ would they be better? I kind of wonder. All of the systems were built
for telco applications and wouldn't need to be better then what the service
required.
There should be additional equipment falling out of the telco industry as
they shut down the old Gen 3 sites/hardware. So maybe in a year there will
be a new batch of interesting widgets from China.
