Servicing
I would echo "Peasacake" and say go to Rotorspan at Droitwich. I use them to look after my Hughes 300C and I know I am not alone in singing their praises.
They will even lend you a car to get home in if you don't have any other option
The quality of service is excellent, Mike sets a high engineering standard and you get the lovely Diana to make you a cup of tea and listen to all your woes. It's worth the cost for that alone.
