I think we have one Mitel with a built in switch, and I was pissed when I heard they sold it 

  I'd rather have a cheap dell or netgear switch (and yes I hate them both) than some who know what the heck it is built in unit.
  I love HP at the "low" end and of course Cisco leads the pack.  Juniper is also a great switch - talk about ability - check out JunOS.  Amazing stuff.
  Sorry - not trying to be a network snob
