Methinks you just need to convince your wife that a Spincade is within your budget! ;-)
Arcadedepot has really nice kits, and so does Dreamarcades. Also, Mameroom. Their cocktails all have a different look from eachother. I'd say if you're going for the classic "Ms. Pac Man" look, then you may want to consider Arcadedepot. They're all good.
But seriously, consider the Spincade..... :-)
