Hmm, wouldn't the DSP filter be good enough for this purpose?
Except for obnoxious PACTOR, there are generally not the 40db over S9 signals to reject.

Out of curiosity, what would one use or need  a 700hz filter for?

P.S.  The filters retail for $145 each + S&H, with S&H being as follows
...
o   Domestic = $6
o   Canada & Mexico = $14
o   All other international destinations (one or two filters) = $18
o   All other international destinations (more than two filters) = $34
