The brothers Zwisler grew up in Indiana, playing Ping-Pong in the basement of a convent. When they migrated to Colorado -- Marty to build custom houses and Ray to make custom wood furniture -- they maintained their love of the game. Several years ago, in fact, they decided to build a conference table that could also be used for Ping-Pong, and the idea caught on. While the price -- ranging from $5,000 to $8,000 each -- may put these tables out of the realm of the average rumpus room, Ray says that it's reasonable for corporate furniture. And with clients like Allstate Insurance, it may not be long before a bounce in the economy signals a bounce in sales.
