I'm a great fan of GPS, don't get me wrong. The modern options have some amazing features.
However, why not take a bit of pride in your flying? Flying an accurate heading that corresponds to desired track, and when visually recognising you're off track, making an appropriate heading change to get back on track to your waypoint, IMHO, is much more rewarding.
With proper planning and airmanship, a GPS shouldn't be necessary. A back-up, by all means. Being comfortable with VFR navigation techniques allows you to actually chill out and enjoy your flying; after all, you're paying a great deal for it. You can guarantee that so long as you're flying head-down in the cockpit, somebody else is. The old "Big Sky" theory doesn't work for everybody...
