I've got a Tru Center. I love it, but it does not necessarily take away the need for corrections. But, as Paul said, if there seems to be the need for constant corrections, the bell crank may need replaced. The tru center does help with movement caused by passing semi-trucks (this was never really a problem for me) but is great for that side wind that you constantly have to correct for. Turn the wheel in direction you want it, hit button, and it keeps you in that direction until you change it. Also, I hear it is good for a front tire blowout to keep the coach stable and controllable. If you can do the work yourself, it can be installed for less than $1000.
