I owned one years ago. It was a post 1964 version of the Winchester model 94, and about as nicely made as any Winchester version then. It did have exceptional wood, and looked nice after a refinish. The receiver, however, had the same problems the Winchesters did with finish wear, and turning colors (the metal used in post 64 actions), so I just buffed it to an off silver.
Nice enough gun, but I traded it for something else years ago. Just guessing, but I would guess it's worth a little less than a typical Winchester marked model, simply because of the Sears name. If there were a pre-64 version (?), probably worth a premium, as are the Winchester versions.
You can find some real bargains with the Sears name. They, for example, offered an inexpensive bolt action rifle that used the commercial FN Mauser action, same as used in the expensive Browning Safari grade rifles, and many customs.
