AV8OR
You can consider the AV8OR (Bendix-King). I have a new one, flown it just once. Good little thing, usable in the car too. Comes with voucher for fresh database update, cables, charger, mounts for plane and car. With Atlantic database on SD-Card slightly over 500 EUR+VAT.
I planned the route on it and flew it later too. It did exactly what I needed. It is absolutely necessary to know the way it works however. I played with it on the ground several hours and thought I am fine. In the air it was a different story, but I guess couple of hours of airborne experience will be enough.
