EB has it for $24.99, so you saved six cents but ended up paying shipping...
It's a neat concept piece, but let me know how the controls end up functioning. Four of the games use four-way joysticks (Galaxian, Pac-Man, Rally-X, Dig Dug), but Bosconian is an eight-way, and sometimes eight-way joysticks get funky when used with four-way games (when you roll the joystick through the corner, unpredictable things can happen).
I will be a good boy and not describe how someone with a CD burner could buy a used Sega Dreamcast for $40 and have all five games running on it via MAME in ten minutes.
