[TowerTalk] Auto antenna tuner

[Noel]

I know this isn't exactly tower related but I'm considering an auto
antenna tuner as an addition to my shack.  I'm sure some of you out
there have some experince with auto tuners and could make some
recommendations as to what make or models to consider.  My requirements
are simple but don't seem to be easy to find. I want an auto tuner that
can handle more than a couple hundred watts, that I won't have to take
out of line when I want to use my amp (600 watts).  I'm currently using
an MFJ 989C legal limit roller inductor tuner but want to be able to
change bands more quickly.  I'm obviously willing to settle for less
than legal limit but want the funtionality of a roller inductor tuner
but without the manual tunning. 

All responses appreciated.
