BF2S Forums Need help buying a projector!

I've had four different projectors.  Here's the basics:

(1)  The two technologies are DLP and LCD.  LCD is more expensive, sharper, and typically brighter ... many believe that DLP provides adequate projection for most applications, but enthusiasts tend to the LCD.  I think the DLP projectors tend to be less in focus on the edges, but I can't recall.

(2)  There is a lot of variation in the types of lenses that projectors use.  So, you need to have an idea of where the projector will be located and what viewing size you want.  Higher end projectors tend to have more flexibility, and lower end (cheaper) projectors are more limited in their projection size/range.

(3)  The bulbs last anywhere from 800 to 2000 hours, and they are very expensive to replace ($100 to $500 depending upon the model).

(4)  If you are purchasing a used model, pay careful attention to pixel divergence - a white dot should ideally have all three RGB colors hitting the same spot, but there will always be some minor divergence.  Before purchasing, look at a test pattern to make sure that the divergence is not so significant that it messes with the picture, and is acceptable for your needs  ... also, look for dust blobs that might be on the picture (these would appear as darker spots on the projection).
