Large sanctuary with stained glass windows, 25 ft cielings, 50 X 100 room, can make it reasonable by pulling shades (not all windows have them though), cieling mounting & projecting onto a 12 X 12 Dalite screen. Both PJs have similar specs, although the Optoma looks to be newer. Toshiba was just discontinued and is now less than half price. Both PJs same price at TigerDirect. Have read that Optoma replacement bulb is only $250, but toshiba name is well respected. Only positive reveiws for the Tosh on Projectorcentral. Can't find any reviews of the Optoma other than on the tiger site. Any opinions?
