FWIW, I have daily access to a variety of driving controllers,
including a Saitek R4 Force wheel, and I always find myself
gravitating towards the non-Force Feedback wheels. The Saitek wheel
is a very nice piece of work -- its smooth digital output makes it a
very precise controller to drive with, and I acutally like the pedals;
its FF implementation in sims like Viper Racing is very good, too, but
overall, I tend to prefer the precision I get from a good non-FF
controller even over the Saitek wheel (despite it's digitial signal
output).
My ACT Labs RS (non-FF) wheel hasn't arrived yet, so I can't give you
any feedback on that, but for me, the bottom line is that I've found
that I prefer a good non-FF wheel over a FF device most of the time.
I know others disagree, and maybe I'm just jaded, but although FF is
nice, it's not a must-have for me. Plus, if you're interested
primarily in games that don't support FF, why pay for something you're
not going to use? Viper Racing is my game of choice now -- and it has
some of the best FF implementation so far, but as I said, I still find
myself using the non-FF wheels more often, even for Viper Racing.
Hope this helps. Good luck!
