From what is posted (reviews), the AE700 has no screendoor, but may have some vertical banding issues. The HS51 has excellent contrast ratio but possibly screendoor. I just purchased the 700 and will have it in a few days. However, I've been tempted to hold off for the Sony. I am extremely sensitive to SD, VBE, and every other negative PQ quality. Maybe thats why I love my 34" Sony Tube. Now if only I can increase it's size from 34" to 110"!?
