For reference, here's the original library which has TinyGPS and TinyGPS++: http://arduiniana.org/libraries/TinyGPS/
It doesn't appear to have any compatibility with the newer TinyGPS++ library which I had been using, but I guess that's not really the intent.
Also I didn't know there were modules commonly available for multiple systems. Mouser has the A5100-A mentioned in the blog for $17 in singles, plus an antenna I assume. I've been using the NEO-6M GPS-only modules from China that run about $10 with antenna. Nice to have more options.
