Very interesting discussion. I myself use SN10 + PDA(SeeYou). Besides
what have been mentioned, SeeYou also leaves traces which are useful
to come back at exactly the same place in wave, etc.

I think the original question is easy to answer.. You can buy
everything you need to make the cable at Radio Shack for less than
$10, so just go for it and see if you like it.

I actually modified my SN10B, Volksloger, PDA cabling two years ago in
order to get SN10 Data into my PDA - This turned ut to be a big waste of
time!

The problem was that SN10 also appended its own pressure altitude data
to the NMEA data stream together with the pressure altitude data from
the Volkslogger. These two pressure altitude data may typically differ
by at least 100meter.

While flying close to the upper airspace boundary, it was totally random
if SeeYou used the Volkslogger or the SN10 altitude to calculate an
airspace warning. This resulted in lots of false warnings when the SN10
produced a higher altitude reading than the Volkslogger, and a single
time resulted in a airspace violation when the SN10 decided that I was
lower than the Volkslogger logged.

Most of the time it was only pure annoying - I decided to rip out the
new cabling at the last annual.
