one of the GPS recedivers im considering communicates according to the
protocol specified in NMEA 0183, Version 3.01. This specification
costs around $300, which at the moment i cant afford. im wondering
whether there are any other methods of doing this. any help in this
regard is appreciated.

See the NMEA FAQ on http://vancouver-webpages.com/peter/idx_faq.html
That is based on version 2 (or so) and my observations of the output
of some receivers. I think the newer versions may add a few new
sentences, and recommend that some older sentences not be used.

NMEA-0183 (any version) is basically plain ASCII text sent at 4800
baud. It should be fairly easy to figure out the content of the
sentences by comparing the data to that displayed by the GPS (and/or
applying some common sense...)

My line of work is systems engineering, frequently on defence systems
and often think that the cost of commercial standards must have
greatly reduced their use. I'm sure the wholesale ditching of the old
MIL-STD series has not been a good thing.
