[Xastir] Who's current on Garmin handheld GPS models?

[Curt Mills]

A bit off topic I guess, 'cuz this isn't for APRS use.

I'm getting ready to buy a mapping GPS.  I've dabbled in geo-caching,
but hunting / hiking / SAR are the main uses.

I prefer Garmin, and have (I think) narrowed it down to the GPSmap 64
and Oregon series.  I want the best sensitivity under tree cover, and
GPS + Glonass.

Does anyone have any recommendations?  I'm leaning towards the Gpsmap
64st.  The 1:100k built-in topo maps are not super-useful, but might
be handy when I travel and don't have more detailed maps.  I figure
I'll buy the Garmin Topo West maps (1:24k) and use those for my main
maps around here.  Halfway-decent street maps would be a plus for
traveling.

Anything I need to know about using OpenStreetMaps with any of their
newer models, should I later choose to load my own maps instead of
paying Garmin for updates?  I saw one comment on the 'net about the
64st not being able to load unlocked maps, but I'm not enough of a
Garmin nerd to know what that means.  Hopefully it doesn't prevent
loading OSM maps or others.

Any help appreciated!
