Ordered wrong size HiPower, what should I do?

I ordered the 119inch Da-Lite Hi-Power Perm-Wall screen from Visual Apex. It is arriving tomorrow. I think I would be happier with the 133 inch. If I try to send it back, it sounds like I will pay a big restocking fee. Should I try to sell it on eBay? The other option is to try and sell it locally on the web. I just don't know what the demand is for a screen like this. The other option is to live with it, but I worry that I will regret the size for the next 10 years. Seating is 18 feet away from the screen, Panny 8000U, white walls and ceiling with huge windows.

Thanks,
Rick

viewing distance is 18 ft.

The projector is mounted on the back wall, 22ft from screen, six feet above the ground. Perfect alignment for HP screen. I think I'm going to bight the bullet and return the smaller screen.

Thanks guys! I'm going to bight the bullet and send it back by refusing delivery. It is Da-lite that is charging the restocking fee. Visual Apex has been pretty helpful. I figure if I keep it 10 years, and use it everyday, that is 3,650 times I will regret my decision if I don't make the change now....

Thanks for confirming that bigger is the right way to go! I was home when UPS came with the drop off, and they are sending it back to Da-Lite. The new screen has been ordered!
