To be honest with you I thought about this for a few months, If you in the
US the best solution is something like an Ascend Pipeline 50 router (no
firewall) ($599), with a crossover (included) to an inexpensive NE2000
card ($40). This is about twice as expensive as a Motorola Bitsurfer
(~$300) and doesn't have the analog ports (but if you want isdn for making
voice calls your a wacko anyway). The reason I was willing to pay the
extra $300 were: A. ping time to peer with router = 30ms, B. ping time to
peer with Serial based internal card or external = 100ms (If youv'e ever
played quake on the internet you know just how much difference this makes)  
C. Extensive automatic connect abilities on the router (which i don't use)
which will save you $$$ if you pay per minute usage charges, D. Really,
Really much easier to set up --- though I read the book to make sure about
some of the security features. E. I've had atleast two people (who got
ISDN lines before me) tell me if they did it again they would of spilled
the cash for the router over the TAs. It's kind of like the difference
between SCSI and IDE.
