Thanks a lot, I just wanted to be sure. The eTrex sends lots of useless 
crap on the NMEA output, the serial converter is probably a bad idea
for more than testing, and I am stress testing my system (Raspberry Pi)
at the moment by playing MP3s and sending stuff over another serial
adapter. So the high jitter is to be expected.

Now I just have to decide between the Adafruit GPS and the Sure
Electronics board. Probably the shipping costs will be most
