After a few weeks of getting/playing my gt 1up, I’m happy..12 courses, and it’s light, easily moved, and doesn’t take up much space. My original arcade sized ‘99 gt was to bulky/heavy, and just a tank in comparison. The trackball on the 1up is the same size, but has a bit of a different feel, but play a bunch, and you’ll figure it out. If you’re on the fence, just get 1..lots of fun..
