I pay £6 per pair for my Kity 260mm blades. And saw blades are £8 each or 25pp tooth, whichever is greater, but I'm in the Highlands with only one saw doctor. He is very busy though with there being quite a few timber yards.
I pay about £9 for 3 12inch blades for my sedgwick to be sharpened. Saw blades are usually priced per tooth expect about £6 for a rip blade and upto £15 for a large fine tooth blade.
My saw doctor calls once a week to pick up items to be sharpened and deliver sharpened items. This costs £1.50 a delivery.
It greatly depends on the size and quantity of your blades. Mine are currently with Dragon Blades, as I was suspicious of the quality I got from Bedford Saw. I am interest in the comparison. It could be that the problem was/is my tables.
