While I am not a telecoms engineer, magazine scribe or salesperson, this
is in direct conflict with my personal experiences.  I live on a farm,
so phone lines are not very good, and have three v22bis modems and a
T2500.  I have had various V32 modems aswell (some costing about double
the price of the T2500) and have only found two reliable modems (that 
will connect at the highest speed possible and hang on until the end
NOMATTER WHAT).  These are the Racal vi2422 (v22bis) and the T2500.

The others have all died on bad lines, either not connecting or 
losing the connection before a transfer (~20 minutes) is complete.
The most reliable v32 modem (a MultiTech) had a dud connection rate
of about 7 in 10 (ie: 7 duds in 10 attempts), with the best v22bis
(Octocomm) getting about 5 in 10 (ie: 50% success).

Your mileage might vary, but rather than relying in PC Magazine, try
to get a few modems on loan, borrow, whatever and actually try them.
I realise that this is an innovative concept, but it will tell you 
which modem will work on YOUR lines.
