TRON was the first modern machine we ever had in my house. I've been lucky enough to play a number of variations of the game, and I honestly think this is one of Stern's finer machines.
Created in 2011, there are 4 editions of the machine as well as a limited edition. Each edition comes with different back glass art. Designed by pinball veteran John Borg who seems to design some of the best sci-fi movie playfields, the game has 3 flippers, slingshots, a spinning target, 3 target-dropping banks, and more.
You can find a plethora of mods for this machine, though I suggest getting mirror blades for the sides and putting in LED lights. Prices are all over for this machine since it depends on which one you buy, but if you're a fan of TRON it may be worth your time to find one.
