A few of my students have used Flight sim x and really liked it, but seems to help more for the instrument rating than for private pilot maneuvers. It could help you with flows and setting up for the maneuvers, but Im not sure how much it will realistically help you to offset the cost. You can chair fly and accomplish this for free.
Does your school have a PCATD? Many aviation colleges have a PCATD which is basically a computer with flight sim, rudder peddles, yoke and com stack. They will usually let you use it for free or at a very small cost.
