Hello,
I first used a (loaned) Garmin GPSmap 60Cx (without compass and
altimeter) and then bought a GPSmap 60CSx (with compass and altimeter).
I never use the compass or the altimeter for mapping, but the extra
features have a noticeable negative effect on battery life.
So if I had a do over, then I'd buy the one without the compass and
altimeter.

I was looking at the eTrex series from Garmin to use for mapping on OSM,
as they seem to be robust, compact and have specially long battery life
(25 hours on 2 AA batteries). The main difference between 20 and 30
seems to be that 30 has altimeter and compass, while 20 doesn't have
them. Is this important when recording GPS tracks to use for mapping on
OSM? Doesn't compass and altitude data come from GPS satellites anyway?
Or an internal altimeter and compass are more accurate?
If anybody here has either of the above GPS units and uses them for
mapping, it would be useful to hear a first hand opinion.
Thank you all for the input. Really useful to hear some real life views.
