I've used both the eTrex and the eTrex summit. The basic eTrex has
everything
you need and is very functional as well as being very cheap ($218 at some
places).

The summit has a barometric altimeter and a flux gate compass. The compass
does
consume more power when its being used but it can be disabled or set to only
turn on
when you move below a certain speed, which can be quite useful in the last
few meters
of locating a geocache.

I suggest the basic eTrex if you don't need and fancy features and just want
your position
altitude and bearing.

(btw eTrex models can use a data cable and output in a variety of formats)
