The other criteria I consider important is good bandwidth when all ports 
are used, and the inclusion of a gig port or a GBIC slot, to allow a high 
bandwidth connection to the master node.
In this respect I think the Extreme Networks Summit24e-baseT is a very good 
It  has 24 of 10/100 ports and 2 gig copper ports.
Edu/government cost is around $1,750
