I have never owned one, but they are rare. I have seen some totally rebuilt 3 speed with overdrive going for $1200 to $1300. My main interest in it is the overdrive and whether it will increase my cruising speed with lowering myc rpms. I want to get my truck up 60 mph crusing speed without the rpms excessively high. But the 3 speed manual transmission with overdrive are hard to come by. I currently have a 3 speed without overdrive, they are not as rare but mine does have sychcronized 1st and reverse gear. My next step is to change the gears in my rear end to see if I can get to my ideal cruising speed. This will be less expensive.
