Yeah i am going to be on a longer trip (few months or more) and i realise there are certain benefits of having a GPS. I think just having one in the luggage is what i'll do 'just in case'. Its just that they seem pretty expensive for something i might not really use.
I see the Garmin ones are fairly popular on this website. They also look to be the more expensive brand, but in saying that, you get what you pay for probably.
If i go down to the local electrical store to get one, are there any brands or issues i should be wary of?
...Maybe secondhand.
