I'd recommend GARMIN handheld GPS devices. The reason is that they have better or almost the best map coverage or accuracy. Magellan maps are interesting (better every year) but still don't have such accurate maps.
I'd suggest the following before buying:
1. Check what batteries the
device uses. Namely, for devices that run on
Li-Ion batteries, you have to buy an extra
battery, which aren't cheap. Even if
you have two, it doesn't mean the device
will work through the whole trip (especially
in winter). If you have a GPS that runs on AAA
batteries, you can buy them everywhere,
although I recommend NiMH batteries.
2. For accuracy, it's recommended that the
device has (which almost all already have)
SiRF III chip or high-sensitivity chip.
Although in practice it doesn't mean exactly as
on paper. Depending on where you are,
(trees, wall), weather conditions (thick
fog) all this affects accuracy, which
can be from 5 - 15 meters. Many
already show how much the accuracy is based
on signal strength. Electronic compass and
barometric altimeter help a bit
with accuracy.
3. Waterproofness is desirable, so you
can use the device even in the rain,
which is even more important, no panic
if it "sweats", if you go in winter from hike
to hut (if not waterproof, you have to
put it in a bag before entering the hut -
highly recommended).
4. How you operate the device. Some
have buttons, rollers, touch-sensitive
screens... I have a touchscreen, and I have to
say it works very solidly (although I
was doubtful before buying). The GARMIN Colorado 300 is interesting, it has very few
buttons, but in practice it doesn't prove to be
very functional, especially for writing
addresses.
5. Cartography. You have those that
show you the map, or just
location and direction. I recommend the former, unless
you have it only for training.
I could list more, but if you browse the internet a bit, you'll find all the information.
I myself have the DAKOTA 20 from Garmin, and I'm satisfied with the device. The problem only shows when standing or walking very slowly, as "fictitious" points are recorded that you actually didn't cover. The other drawback is visibility in strong sun. It's true, as written, that it's harder to see, but you just turn away from the sun and it's  The problem with us is also the price. Garmin has very high prices. I got mine from England for about 120 € cheaper than here.
If you have some specific question, ask.
Best regards
