Some Nikon Film Lenses have compatibility issues with Digital-SLR bodies. The same lens might work well with some bodies but not with others.
If you have a way of getting the exact model numbers of the lenses you can find which Nikon Digital-SLR cameras are most compatible with those lenses.
There is also a conversion factor of 1.6 x involved. This effects any of her film lenses used on a non Full Frame digital body. The focal length of the lens is multiplied by 1.6 changing the total "zoom" of the lens. For example... a 18mm-70mm zoom film lens works as a 29mm-112mm lens on a digital body.

Any Plasma TV being moved a considerable distance needs special care. The unit should not be laid flat...always kept upright. If you are having professional movers move it it should be rapped and if at all possible in a box.

When it comes to projectors...the theory is a little different than used n LCD/Plasma TVs. It is not so much how far as in how close.
One thought is with 720p resolution projectors the viewing distance of less than 1.5 times the screen width can show more pixelation and artifacts. A higher resolution of 1080p would allow closer viewing with sharper imaging.
The farther away the sharper both would appear.

Most projectors come with different input options from just regular analog/composite(RCA Type) to HDMI. Projection output varies from SD (Standard Definition) up to HD at 720p or 1080i.
Projectors usually do not have built in tuners, mostly inputs.
