Assuming we are talking about the same Yahama that has been out for at least one year, then I would be inclinded to pass on this projector. This machine while having a good picture, is already old technology compared to whats out. It neithers has the new HD-1 chip or the new color wheels that help reduce or eliminate rainbow artifacts.
When this projecotor was first introduced at CES about 2 years ago, people were very excited about it even though the newer types were coming out. To me, Yamaha came out with this much to late. I must say one thing about his projector, it is very quiet.
Hope this helps
