| 1199127 | 2011-05-03 08:47:00 | Hi A local community group wants to buy a data projector. What are the specs/issues to look out for - eg in "the old days" cine projector bulbs were both prone to break when moved whilst hot, and expensive to replace. Any and all comments/info gratefully received including recommended makes, and model to avoid. Thanks |

| 1199128 | 2011-05-03 08:58:00 | Well we've used quite a few of the ViewSonic data projectors and they've been great. No problems so far in almost two years. They come with a 3 year warranty and the replacement bulbs are some of the cheapest I've seen. The only thing I don't like about them is the throw distance as this can be quite high if you want a decent sized projection. |

Thanks CY - what sort of price are we talking about for the projector and replacement bulb (sorry - I know I'm being lazy!) |

| 1199130 | 2011-05-03 10:32:00 | That depends on how bright (lumens) you want and what sort of resolution you want to project at and if you want widescreen or 4:3. The resolution can be svga (800x600), xga (1024x768) usually. They will accept higher resolutions but will downscale to it's native res. Svga is the cheapest obviously. They start at about $900 from memory. Not sure on bulbs as haven't had to replace one yet. :pf1mobmini: |

I think the organisation will have a second take on "They start at about $900" - an "expert" told them "they're relatively cheap nowadays". Thanks Cy Anyone got anything else? |

| 1199132 | 2011-05-03 23:00:00 | My Toshiba DL SVGA just expired a bulb, after approx 3500 hrs.....think it costs about $450 to replace.... Throw distance is important if you move the unit around as room size comes into play!... We have a BenQ here at work which is XGA, if I were to buy another unit, i would get 720p at least and wireless! |
