After doing some research I decided that the projector I wanted (my first) was the Wimius P28. Got lucky (took a chance) and found an unused/open box P28 for less than half the new price, even with the mfg discount, plus free shipping. The projector arrived three days later in its original box, plastic wrapping, etc. The only problem, missing the instructions. But the P28 was so straightforward and simple to setup and use, I found that instructions were unnecessary. Wow, was I surprised at the crisp clear picture. Even in full daylight the picture was excellent. For my first projector purchase, I couldn't be happier. I turned right around and purchased a P18 for another room. Can't wait for it to arrive.
