I ride a Trek 750 with rigid fork and rigid seat post. I probably do more off road than you plan to do, and I've never seen the need for suspension.
If I was riding on trails that I thought I really needed suspension on, I'd get a mountain bike and save my 750 for lighter trails and road.
Save the weight, save the money.
