Have you tried a telebit recently?  I use a TB+ to talk to a T2500 on a
Cisco terminal server and have not noted slow echoing.  The SLIP issue
is likely to become a non-issue now that the PPP RFC has been issued.
I expect Telebit to have some sort of SLIP support relatively soon since
there is a large demand for it.  No guarantees from me though.

I disagree.  The performance edge of the Telebits is so great I would not
consider a V.32 only modem.  The defacto standard that I see is PEP and
not V.32.
