The latest version of USR's Dual Standard also has V.42bis (in V.32 mode only,
I believe) and MNP5 (in either HST or V.32 mode).  If all you need is V.32,
go for the cheaper one.  However, if you are only transferring files in
one direction at a time (i.e. send one file to him, then he sends one file to
you, etc-- not two files being sent simultaneously), then the HST offers faster
speeds-- up to 14,400 bps, nominally (before compression).  And if you get
the Dual Standard, you will still be compatible with The Rest Of The World
with V.32.
