Selling Projector Advice

I am going to be selling my Epson 8500UB projector with ceiling mount on ebay shortly here and I also have a 100" fixed screen with a black border and was wondering if people think I should throw it in on the listing as well?

I don't know the gain on the screen, if I don't include it. I could try selling seperately, just not sure what's my best plan.

I also have a 50' HDMI cable I could throw in if people think that helps.

Any experts on this?

The company I work for, AVI-SPL, has a division called Projector People, I would give them a call. It would probably be best to call the main line at 813-884-7168 and ask for that group. They sell projectors all the time, including some of our used rental gear. Let me know if they can help you!
