I'm considering it... need to sit down and do some calculations about field of view etc.
Diagonal on 8x10 is 12.8 inches... I'd need it to cover diagonals of 10.4 and 11.7 inches, and I'd be disappointed if it didn't. I don't need any wiggle room for movements. I'm working now and will be busy tonight, but tomorrow I'll try to sit down with a calculator tomorrow. Don't hold it for me if someone else makes an offer.
If I decide to buy it I'll pay your original price.
