Today on a market i found one with rotary dial, about $60 was a little expensive in my opinion, but still... Havent seen one for sale for years.

The handset cable was trash, the rubbe rjust fall off, and the dial had to be tuned. When that was fixed Everything works.
This was not an easy phone to take apart or put together! On the other hand it is lightweight, and works well.
