I have a Garmin StreetPilot 3 - an older model - but a good one - it's in the Jeep, I use it to find fire calls from time to time. I also have a Magellan 315, which I'd not buy again.

All in all, I like Garmin's interfaces better than Magellan. I have a Magellan handheld and it's not so great in deep woods.

I also used an eTrex (garmin) and it did real well in heavy forest canopy - and nice fast lockons too!

Battery life is a BIG issue with these handhelds, also the internal compasses STINK.
