I've got the Sony HS-20. So it's not quite as ancient as yours, but it's pretty close
. I still remember going into the local A/V stores and seeing the 10HT back in the day -- it was a great projector.
I have a big living room with lots of windows, light colored walls, and sadly, a white ceiling. I also live down in Austin, so basically I have to wait until about 9 pm right now before I can even think about firing the thing up
Plus, my panels are clearly out of alignment (my HS-20 has already been to Laredo once) and the picture is very soft. Time for an upgrade!
