Not sure what your budget is, but if you can swing it, Dell has some nice switches that I've been using for LANs for quite some time without issue.
The Dell PowerConnect 2324 is the specific switch we've been using (currently have two of them) and the gigE ports definitely come in handy for tying into a gigabit backbone for the network. Right now they're going for $112 + shipping (holy crap, might be time for me to pick up another!) and are 24 ports of 10/100 and two additional 10/100/1000 ports.
