From my experience, I would suggest the following:
Cisco 1600 or Compatible Systems MicroRouter - both of these will have
the CSU/TSU integrated inside!!! And they are much cheaper than what you
might think
Hub - NetGear by Bay Networks seems to be a fairly inexpensive solution.
We have a tendency here to use cheaper stuff, but when it comes to our
customers, NetGear is our choice
The good news is: That would be all you need!!! The router obviously has
a 10BaseT ethernet connection on the back as well as an AUI (usually) to
connect straight into the local network...easy as pie :)
Good Luck,
