for the garmin i only use the free motion based account...i pretty much just use it to save my routes on google earth. some of the other stuff it has is cool, but not worth paying for. youll be happy with the garmin. ive had mine for a little less than a year and i still think it rocks!!!! and it isnt THAT big....its not itty bitty, but not huge either...one bummer is that for all of yer doubles yer gonna need a way to power it past its 12 hour battery lifespan....either that or get REALLY fast...
