Hey scoffey,
Sorry for the very slow response, I only payed about 55$, I dissembled it my self to save costs and just gave the bed knife and the reel. I basically just googled 'sharpeners' and rang around till I found someone that knew what I was talking about. The one I used was in coburg, but I had a quote of 200-250 from a mob in hoppers I think.
Thanks K-balm, shes still purring along well, still enjoyable mowing my lawn
