   Now that you've described your needs in greater detail, I think I can 
provide some useful input.

   Even if your async speed is limited to 19.2kbps, it may pay you to invest 
in the fastest modems you can get a hold of.  Data comression is a big 
advertising feature these days, but its effectiveness varies from the claimed 
4:1 potential right down to zilch... a V.32bis modem, operating at 14.4kbps 
physical port speed, won't exceed a throughput of 1800 CPS on compressed 
data, with or without V.42bis data compression.

   If you *need* the maximum throughput possible, buy the fastest dialup 
modems out there (v.32bis).  You could argue that you could save a few bucks 
by sticking with V.32 and going that bit slower, or relying on data 
comrpression (if you *know* that your transferred data will all be text), but 
it's best to know for sure that you won't kick yourself in the future for 
making the wrong decision.
