I really don't know much about this. I bought and then later figured out I didn't have room for it. The guy said the tubes had 10000 hours left on them and he included a ceiling mount and a logitech remote that is very nice. I will say 1500 + shipping because I saw another guy asking 1900 for it on this site. I saw it working at the guy I bought it from and he had it with a 10 foot screen and it looked great. Let me know if the price is not good, cause I really don't know much about this. email me at firstname.lastname@example.org if you are interested. Thanks.
