Just remember that "home" alignments have only one thing going for them--a motivated mechanic.
Everything else is generally of MUCH lower grade. The equipment is usually crap, the pavement the car is parked on isn't level, and a tape measure hooked to the tire tread isn't particularly accurate. The slope of the driveway is enough to screw-up "home" alignments.
I'd be looking carefully at tire wear, and considering how the "new" alignment can correct the geometry to reduce future tire wear.
IN GENERAL, "home" alignments are good enough to drive to a real alignment shop after installing a heap of fresh front-end parts, and no better. There are (rare) exceptions.
