Panasonic, known for developing projection solutions through the years, offers another projector alternative in the AE100U projector. This projector throws a 100″ diagonal image anywhere from 10 to 20 feet.
The PT-AX100U weighs in at 10.8 lbs with a HxWxD of 4.4 x 15.5 x 11.8. This is about 2 lbs heavier and a full inch larger on each side than the Sanyo PLV-Z2. However, a move towards this size and weight appears to be becoming a standard for projectors in this class.
