Arcade1Up systems are mighty expensive these days, with some going as high as $600 or even $700. Walmart has a great deal right now on the Simpsons arcade cabinet, complete with riser, at just $400--down from $529. It's a sharp-looking cabinet that comes loaded with The Simpsons arcade game as well as Simpsons Bowling, and it includes four-player support.
One of the best beat-'em-up games of the '90s, The Simpsons lets you play as Homer, Bart, Lisa, or Marge, and if you have a full squad, you can control them all at the same time. This version includes a riser, as well as a lit marquee and online multiplayer support.
If Simpsons isn't your thing, you can also get a discount at Best Buy on the Ms. Pac-Man & Galaga Class of 1981 cabinet, discounted from $600 down to $500. It's based on a real split cabinet from 2001, featuring artwork from both games.
