you could always buy them at garage sales and antique shops. I rarely pay move than $5 and they are a great place to learn to sharpen a saw. you can buy a lot of those for the price of one new saw. and it only takes an hour or so to restore one.
Thanks for your reply. My concern with buying a saw that requires refurbishment or even just blade sharpening is I am brand new to this and I have never sharpened a blade. Also I don’t really know what to look for when evaluating a used saw. So really at this point, my preference is to buy a new saw.
Thanks again for your suggestions.
