Hmm, one UK EC120 owner who I spoke with was understandably bothered by the price managed to work out who the manufacturer was and approached them direct and paid about £25 per belt. I think they are near Heathrow if memory serves? This was a couple of years ago.
So, let's get this right...............
Cost from manufacturer = 5x£25 = £125
Re-Sell to gullible customer = £13,000
