Best way to sell a secondhand GPS in UK

[Runnerbean]

I'm currently trying to sell the GPS out of my aircraft and I'm not getting much interest on the UK iteration of a well-known auction site. I'm aware PPrune doesn't allow commercials - any suggestions where I might best advertise it?

I have always found AFORS to be very effective.

Excellent, thanks - I had no idea that site even existed
