The fact that it comes with 2 spinners, a track ball and 2 sets of Street Fighter style button layout (Joystick & 6 Buttons) is already worth the $500USD (Probably about $700CAD) in my opinion because it has decent looking "bones" that you can use to upgrade and mod it to your heart's content.
I may consider it just as a good supplement or flat-out replacement to the Arcade 1up cabinets... UNLESS the whole kit is complete garbage.

And here's a video of Retro Ralph after he modded his unit:
What do you guys think? Worth the price just to have a low-cost cabinet to mod, or actually worth to keep stock?
