Finally bit the bullet and bought the projector. Got it for a total price of P39,475. Overall, I'm really impressed. Loving the picture quality but really surprised by how good the Harman Kardon speakers are. Now I just need a proper projection screen and wall mount.
And oh, for those who asked, no demo unit available for both branches. Z4 Aurora lang talaga meron on-hand and for testing. I had to coordinate via their Shopee account to get the unit from their Head Office to the retail store on the same day since I wanted to do it via Credit Card purchase. Head office is cash basis only.
