I own a 120" from apex. It is a good screen from what I can tell. I recently retrofitted it with spandex fabric because I went AT route. The picture quality on the original was significantly better, at least to my eyes.
The frame is made of aluminum which is a big plus in terms of weight, keeping the screen well tensioned, and the need for bracing in the middle of the screen often used in wooden frames to prevent warping.
My PJ is Epson 8100 which is the model one generation before yours
