Gargraves looks nice and matches Ross switches, but I wouldn't jump into that as a beginner. It takes some work and is mostly permanent. Scaletrax looks nice but does not have much variety in switches. Ross has the largest variety of switches, probably followed by Lionel Fastrack.
It is tempting to start with plans for a big & elaborate layout, but many people have bitten off more then they can chew and they get discouraged.
Better to start small & simple, and expand as you learn.
