...Sorry, I was evaluating this product, but the time they didn't support Windows 2000, so I went with a different product. (their currently product should have w2k drivers..)

I actually ditched the serial gps unit from sony BECAUSE of it's priopriotary nature... the pcmcia card though wasn't proprietary and could make your program think it was just any old gps...
I haven't seen the unbundled versions anywhere, but I haven't tried to look too hard.. try and do a search on the major search sites, if it's out there, I'm sure you can find it... still, that price was VERY reasnable...
