Its tough to assign a percentage for improvement. Generally by iteself, and I'm probably going to take a bit of heat for this
, the Sharp will yield a better picture. You can do a lot to an LT150 to improve its standalone performance (such as HTPC/scaler/anamorphic lens, etc...) but there isn't anything you can do to the main engine of the projector, which ultimately is going to determine its overall potential. The Sharp is a native 1280x720, with the RGBRGB color wheel. Because of this, rainbows are going to be greatly reduced and color saturation and black level is going to be greater. If you were to add a scaler and such options to the Sharp, its performance would be even better yet. The question comes down to price range. If you can afford the Sharp and accessories, go for it. You won't be disappointed. If it is out of your price range, the LT150 may be for you. It is a great performer at a reasonable price.
Thanks!
