ViewSonic LS832WU 5000 Lumens WUXGA Ultra Short Throw Projector with 1.3 Optical Zoom, H/V Keystone, 4 Corner Adjustment, 360 Degrees Projection for Auditorium, Conference Room and Education

This is a good and portable UST projector. I use it for VJ'ing live music shows, and multiple venue tech's have remarked that they're impressed with it. The fact that it fits snugly in a carryon-sized hard-shell case has been crucial for touring. The throw distance is remarkably small, even for a UST. However, there is one very annoying caveat with this model, which is that the main point of focus is not centered in the frame, but rather at the bottom of the image. This is significantly more noticeable when using the projector with a larger throw, but it's apparent even at smaller sizes. I've been told that I should reach out to the manufacturer to see if I just have a bad unit, but I'm not so sure. Would definitely have paid a little more to avoid this flaw, but it's also on the cheaper side for bright, FHD UST so I'm happy with it. If portability is a factor and your budget doesn't go higher I would absolutely recommend it.
