Personally I like the 76Cx (pictured in
>>465886, along with my GNSS simulator). Tough/durable, waterproof, allows me to power it directly off my snowmobile/motorcycle, good mounting options, easy to operate with gloves on, capable of using mapsets that work for my applications.
Make a list of your requirements.
If mapsets are on your list of requirements, see what brand(s) are compatible with the maps you want.
Narrow down the style of GPS you want, and pick the specific features from there.
You might find the $100 budget GPS does everything you want it to. If you can't live without the latest features, expect to spend $500 or more on one.
