I am not advertising for DX but I have bought 4 with good results and their units have a 5 V regulator on it. Some have even a TTL to RS converter on board. Bert Kehren In a message dated 5/2/2014 11:40:47 P.M. Eastern Daylight Time, [email protected] writes:

I had come across the Ublox 6M when I was looking earlier, but I misunderstood the data sheet and thought it was only the expensive ($135) LEA/NEO-6T versions which provided timing. Definitely worth a closer look - the NEO-6M is specced at 30ns RMS which is good enough. The power consumption is a little higher than I would have liked at 37mA/3V, but still rather less than others.
