TRY MITSUBISHI. I suggest you go for the 3,000 lumen MITSUBISHI XD490U which could managed well with a gym's dimension. It has the TI DARKCHIP 3 which is superb for cinema-grade resolution, a versatile native XGA resolution with DVI connector, a zoom function for up to a 150-inch screen, and at a price of not more than P105,000. This is the only XGA DLP projector I knew which has the Darkchip 3, as if its being geared for both home theater viewing and as a multimedia beamer for that extra lumens and giant zoom.
If you go for Epson or Infocus, you'll be tolerating the monopolistic, high-price policy of its Philippine distributors who doesn't care a whet if you buy or not because they hold the exclusive stocking. Their pricing is very questionable ethically because they could imposed as much as 45 percent of a profit margin to any one model - this means that a unit which costs anywhere in the world at an MSRP of around P68,000 could be sold by the local Infocus or Epson to as much as P140,000.
