Goes for $125 new + shipping and tax ... yours here for $50 less.
Good used condition ... main item of note is the previous owner removed the "washer" at the tip meant for select saws with a "T" miter slot. If that's a must have for you, you'll want to skip this deal.
At a minimum, this miter will fit the following models (provided your saw top has not been modified)
