Projector 2000:1 Contrast over 2100 lumens and at least 1024x768 resolution native

Need good quality so I can offer a one year warranty on product.  I also sell a extended warranty so I need something of good quality to help our company keep our doors open. As you know our economy is not doing the best so I do need something that is cheap and of good quality.  I would like to purchase a unit that I can mount up and use as a display that shows the good quality of the unit.  This will allow it to sell itself.
