WNEP 16 reports from east central Pennsylvania that a modular home builder near Selinsgrove moved into a facility vacated by a previous modular home builder last year in Snyder County.  Durabuilt owner Kevin Hahn says they have already hired 20 additional workers since opening, increasing production by 40 percent.  Despite the overall slow housing market, Hahn says his company believes there remains a need for new homes on the market, and he emphasizes the importance of service.  The company expects to hire ten additional workers before the end of the year.
