NMEA GPS Receiver Recommendation

[GHA]

Any suggestions on 12V/5V dc converter? had one from Ebay but very hot and eventually dead.

Both these have been OK so far, stuck a variable load and the voltage stayed stable but can't remember the current when it started to tail off, but enough for what they get used for >>
