Do you know the typical power draw of the GPS units?

It's a pretty large market out there, so it ranges all over the map. The FV-M8 that I have uses about 60mA. The u-blox use about 40mA.
However, one of the reasons I like the u-blox is because it has some nifty shut-down features that let it go to sleep and wake up periodically, all on its own, so power usage becomes much less important. Here's the link:

(Note that if you wanted something like that, you'd have to be able to do some programming in order to support the extended features. It's pretty easy, and I can advise, of course, but without having the GPS unit in front of me I'd be a bit limited. Are you comfortable with that?)
