Ok, the bulb in my 6 or so year-old Optoma projector has finally died. No point getting a replacement bulb so I'm planning to replace it with a HD one. From some brief research on line it looks like the best replacement options are also Optoma's - either a 720p HD67N for about £500 or a HD200X for about £700.
Anyone know about projectors and advise on whether 1080p is worth the extra or other options I should consider? My screen is an 8ft one.
