Compact Foam Sprayer. Graco claims that the Reactor E-8p Portable Plural-Component Sprayer is the first foam sprayer specifically designed to apply the new no-heat polyurethane formulations. Although it weighs 96 pounds, the wheeled unit is skinny enough to fit through a doorway, and it has telescoping handles so two people can carry it up and down stairs. The 15-amp motor plugs into any standard 120-volt residential outlet. The sprayer alone costs $6,850; with a gun and hose, it goes for $8,250. Graco, 877/898-1241, graco.com
