I'm new on this list but I think I can help here. You might be forced to
use a router because some college campuses limit the number of IP's that
can be leased to one port. With a hub or a switch each machine connected
to the device must obtain in IP from the DHCP server. With a router,
only one IP is needed since it uses NAT to supply internal IPs to your
machines. E-mail your tech department to ask them if it is OK to have
more than one machine on a port. If it is, get a switch (they are cheap
enough that there is no reason to get a hub) otherwise you will need a
router. I have a couple Linksys routers that work well and can be had
for the sub $50 range.
