I am really stuck between 2 options:

Option 1:

Used Panasonic PTAE1000U with 500 hrs logged on the lamp $950


Option 2:
New Sharp DT-510 for $620

Thanks in advance

Do NOT buy used projectors...You need warranties....Some electronics are ok to buy used....BUT...unless the projector was say under 400$ I wouldnt bite.

If you've narrowed it down to those two I'd go with the Sharp.
