HI DanLee
I live in the Hills District too.
I also got a quote on the weekend form a place in Rouse HIll
and it was $200. They said they send it down to Melbourne to get sharpened.
$200 includes new bearings, Reel and Bedknife sharpening and they also set the new blades up.
I used to go to the Sydney Roller Mower centre too. They are closed down now.
The bowling club at Baulkam Hills could be a good place to start. IF I egt a chance on the weekend I will ask them.
Cheers
