I've got a 92" 16:9 Da-Lite Contour Electric and I'm very happy with the overall quality. The motor is quite smooth and makes a "vrrrr" sound that is not unpleasant. I don't have the tensioned option but, honestly, the quality of construction is such that I feel tensioning isn't a requirement in my case. My screen is almost perfectly flat and is perfectly still when in use. If you've got the budget, then spend the extra $750-$1,000 for tensioning, but if you'd like the $750-$1,000 freed up for other parts of the project, then you can skip it. In other words, for someone on a budget, a $750 subwoofer would boost the home theater experience far more than the tensioning option would
