Garmin GPS V all the way. Easy to use, lots of features, nice size screen, pleanty of memory (I have a III+)
I wired an auxilary outlet on my left fender for constant power. Batteries vibrate and fail.

The Garmin Etrex Vista has a digital compass and baro altimeter built in - great features. Without a compass, you must be moving to derive a course to the target. With a compass, the unit can "point" in the proper direction of the target while standing still. Also, you have constant situational awareness as far as direction when ya stop - cant do that without a compass - it's worth the extra $$.

 

Here ya go, this is where I got mine (plus pretty cool website) :

GPS or a MAP?? I use a map, Greg uses a gps and we still end up in Michigan no matter where we are trying to go![img]i/expressions/face-icon-small-blush.gif[/img]

 

I almost bought the magellan merridian because of the smart media card option until one of my students told me he returned one cause it made his pants drop even lower. thus for the size option I chose the etrex legend. It is not expandable but does come with a pretty respectable base map built in plus the option to add more maps. I also like that It comes with the cable to download to pc. After each ride I save the tracks onto my laptop so I do not ever use anymore than 3% of the memory. Then when I want to use the tracks again I just send them back to the legend unit via laptop.
I alst really like the one handed usability of the etrex.
Hope that helped

 

I own a garmin and it is super easy to use affordable and very accurate! One of my best investments.

 

E-Trex, easy to use, only complaint, when using the Garmin handlebar mount on my Banshee, the batteries vibrate and the GPS has to be re-started. This is only when taking hard hits though. My E-Trex has also proven itself mud-proof.
