The light from the uncovered window is going to compromise picture quality, especially black levels. You might consider a remote controlled motorized honeycomb blackout shade being installed in it, those look nice and the remote makes it easy to close it when you are using the projector.
If a blind can take care of that window light, I'd recommend JVC for the best PQ, and some dealers have the RS540 in the upper end of your price range, or buy a recent model used JVC. If the window must remain unblocked, I'd go with the Epson 5050 and use it in one of the brightest modes. I have both machines at my theater at the moment, and the Epson looks good if you have never seen a JVC picture.
