Everybody has a price point they would like to meet, however the benefits of task specific blades far outweigh the initial pain of the price.
Longer life/ fewer sharpenings/better results. Let`s assume, that like many of us, you don`t have a 3 or 5hp T.S. Putting a 24T rip only blade on an "average" 1.5 or 1.75 hp T.S. makes a CONSIDERABLE difference.
If at all possible, spend the $`s for blades and take the time to change when necessary. JMO
I have a manual circular saw sharpener and it does OK. I can grind faces and tips easy, although I generally only do the face. By the time the blade would be bad I have had many sharpenings and it is do for replacement anyway.
My fine tooth blades go to dynamic sharpening via UPS. I don't have a diamond wheel for doing them and it would take 10+ sharpenings to make it even, not counting my time and forgetting the better job done by the pro's.
