The infocus SP4805 is an unbelievable projector for its price. It contains the new DarkChip TI Chipset. This unit does have the actual component video inputs which is an improvement to the SP4800's adaptors. I would not recommend taking this projector over 120" due to its low resolution. Contact Vutec or Dalite about a screen. You should be able to get a fixed 103" Screen from Vutec for about $750. The projector retails at $1500. Make sure that you get the right screen for your room. The more ambient light that you can control the better. Good Luck.
