We have a 16 port model that's rack mounted and cost around $400. It works better many of the more expensive multiport serial cards. Paired with conserver, it's a really nice solution. Conserver's logging is great... I've used old dedicated terminal servers in the past and they can be a pain to deal with. The newer ones are probably nicer, but are also lots of money.
