KISS? or ... why a wheel?
On a smaller boat, I cannot see any advantages of a wheel over a tiller, except that the tiller will seem (to some) to be more intrusive in the cockpit. I think the wheels are generally more of a pain, personally.
Think of the feel and the simplicity/reliability you are gaining by using the tiller...
Just my $200 (2 cents adjusted for marine use) ;-)
