Tom, I bought a Tyzak saw in the mid eighties from some woodworking store in Conn. while on a road trip. I still use it, even fact I just cut half blind dovetails the other day for vanity drawers in curly maple. I don't know of the resale value, but I find the saw invaluable. I think I paid $30-40 dollars back then?
This is my first post, looking forward to communicating with all of you.
