Could it still be the color wheel if the image looks fine on the screen? I found a place in CA that will replace a color wheel for $200. I may consider than as my bulb is fine and I have an unused spare. If I decide to get a new projector, I the Benq W1070 looks great but it is going to be too short a throw for my room so I am probably going to look into the HD20 or HD25. They have a similar throw, but not as much offset so I may need an extension for my mount. Thanks for the response!
Edit: turns out it was the color wheel. It can be fixed for $125 parts, $85 labor, +40 shipping. So $250 total. Not sure I am brave enough to try replacing it myself. So I guess I have a decision to make.
