Oh, ok.  The term reacharound could be construed to mean something entirely different than what you meant.  If you want a switch on the back, do it.  I bet you're going to have to pull it out from the wall to service it anyway.  I wouldn't spend extra to do it.  Hell, what if you leave it off by accident, you've got a reacharound to get it back hot.  Now, if the cab line cord was hard connected, I would say it was basically required to have the switch.
