Accuracy of any GPS module below 10 meters is questionable in my limited
experience, but I've had good luck with UBLOX modules like this:

http://www.ebay.com/itm/-/360986417401

Not a seller I've bought from, but pick one from ebay and chances are
it'll wrok fine. The UBLOX modules are nicely configurable so you don't
need to parse tons of data if you don't want it. Update rate is also
configurable, you can get 10 per second if you want.

Cheerful regards, Bob
