Low cost GPS module - which have you used before?

I'm interesting in getting two GPS module for my Arduino. The one on Adafruit/sparkfun is kind of expensive. Has anyone used the cheaper ones on ebay and elsewhere, and can you give me some feedback?

This is the expensive one from Sparkfun: https://www.sparkfun.com/products/11067

Here's two cheap Ublox NEO-6M: http://www.ebay.com/itm/Ublox-NEO-6M-GPS-Module-Aircraft-Flight-Controller-For-Arduino-MWC-IMU-APM2-/200911914297 http://www.ebay.com/itm/1PC-Ublox-NEO6MV2-GPS-Module-Aircraft-Flight-Controller-For-Arduino-New-/221269070805

They both have I2C interface, which I suspect is how I'll be using the GPS unit to transmit location data to another Arduino unit. They both include the antenna. I'm not sure what else I might run into. If anyone could give some insights on these GPS units, I'd appreciate it!

I have always used over >30 projects the SKYLAB SKM53

Works brill set to 9600 on serial 4 wire interface 5Volt compatibility and the tinygpsplus library has no trouble with it at all…

    1. happy coding

you can use UB501B it cost you around 12$ in indian price. It just take TTL input read gps value
