We have been happy with cisco.  We tried Xyplex and a couple of others.  I
recommend that you get the terminal servers in house and try them out
before you make any decision.  There are many things that don't show up on
a spec sheet.  We have found that alot depends on exactly what you are
doing.  We would have put up with some of the Xyplex strangeness to get
the 8 wire async lines if we were attaching alot of serial devices.  It
has been so long since we did the evaluations my comments are pretty
general and probably don't apply to current products.
