With IP Setsuzoku, speed will not be an issue (but if you wanted
speed, you probabably wouldn't be going with IP Setsuzoku in the 
first place), so use whatever is cheapest and works OK with your
BSD box.

A router provides better throughput, usually, but since this is not a 
high-speed link, I don't think you're losing anything.  If it was
a committed 128K rate, that would be different.

If you have any plans for a 128K ISDN line in the future, go
with a Yamamaa Net Volante (RTA-50/RTA-52).  You can use it for that,
and will get better performance than a TA hooked up to a computer.
