large screwdriver removable bits

[zapper]

Does anybody know where one can purchase a extra large long screwdriver with removable bit ends?? My buddy has one but can't remember where he got it from. I've seen the ones at Sears but Im looking for a lager one for more torque and accessibilty. The larger screwdrivers they do have are not bit interchangeable. Thanks

Do you mean one like this? I have this one, and it works great. I also bought one of the soft handled ratcheting screwdrivers that you can put different length shanks into. These are the only 'long' interchangable bit screwdrivers I've seen personally.
