Interested in sharpening my own carbide saw blades (5" - 12"). It takes a 65 mile trip now to get them sharpened; can't afford the gas or time any more. Can a guy buy a decent quality sharpener in the $200 - $500 range? I'm not interested in going into business so the commercial types are way out of range. Just a machine capable of small runs of blades. Please, some comments. Thankyou, Ted
