hi,havent chkd out the first two ,the pana AX200 ,i thnk does have good reviews ,,,,i own the optoma HD65 since 1year ,its quiet good ,i use it with a onkyo 504 DVD player ,the signal is routed through the AVR (onkyo 875) via Hdmi to the HD65 ,,the upscaled images are extremly good ,,though the HD65 is 720p it does accept 1080p,,i pikd it up for 65k (bangalore) + abt 6k for celeing mount + 6k for Hdmi cable ,,,,i thnk for the price its good,,,,,but do consider the HD80 at abt 1.5 L and avoid future upgrade!!
