Garmin Edge 800 used, how much should I offer?

[Psyclist]

Found a used Garmin Edge 800 with standard bar mount, usb cable and 4gb micro sd card with maps. Doesn't come with the heart rate monitor on cadence sensor, there's a tiny pixelated (rather unnoticeable)
part on the screen.

Just wondered if anybody can give me a ball point price to offer the seller which is reasonable.

I'm not fussed about cadence or heart rate anyway. Maps will do.

Half the cheapest new price you can find? (Or maybe 40% of that because it has a damaged screen.)

Sounds fair. Thanks for the reply.
