If you're going with serial get some EdgePort multiport adapters.  I've used
their 4 and 8 port adapters and they're GREAT.  It's MUCH better than using
multiple single USB-serial adapters, if only because of avoiding the
software driver NIGHTMARES.  Get two 8 port and one 4 port adapter and only
have to use ONE software driver and three USB ports, most likely just
chained to a single hub.
