We've been getting our BNC to N connectors (and the coax) from a local
hardware store rather than an electronics store.  BNC connectors are
fairly common, so thin ethernet is a big win.

The thin cables do put more of a length restriction on your network as well
as a reduction in total number of stations.  Maximum segment lengths are
reduced to 185 meters vs. 500 for the thick cable.  It is also recommended
that the total number of stations on a cable segment not exceed 30.

Now if only more vendors would put the BNC connectors on their controllers
the way 3COM did...
