The price difference has really become almost non-existent--one thing
that we've found to happen with some cheap switches (a year or so old,
hasn't happened with newer cheap switches) is that if one moves a computer
from one location to another, the switch seems to take its time flushing
its tables and the box won't immediately be able to get an address.
It's only happened once or twice with a VERY cheap Linksys (again, the
switch is probably 1-2 years old, and this problem might be fixed by
now).

I should also add that we never fully determined that was the
problem--it was usually a matter of trying this and that and eventually
the box would get an address and only afterwards did we think of the
switch as the culprit.
