I cabled and equipped a LAN at home for less than $1000, for 3 machines (2 PC's, and one `other') (admittedly 10b2, not 10bT which is what I would go for today). I take it you are talking about MAN/WAN solutions rather than LAN solutions? If that is what you are talking about, then it REALLY depends where you are ... it costs 400 pounds (about $600 US) just to INSTALL ISDN in this country :-( > you compared to the ethernet solution, considering that the $400 non-ethernet > solution compare to an ethernet one.

Yet again, it depends on your application ... even if you buy a high-speed serial card, you still need the equipment to attach to it, which can be even more expensive. If you compare the overall cost with an integrated TA/router (take the Ascent P50 or P25 for an example), and the advantages/disadvantages for your particular application (i.e. the fact that you have 1 pc which causes problems if you reboot to change the kernel or if it crashes), then non-PC solutions become attractive.
