I need to change to digital projection, I occasionally give talks to garden
clubs and have a slide projector but have found it increasingly difficult to
get hold of the slide film so last year bought a DSLR camera, very pleased
with the pictures but at present I can't use them!

Grrk. I have just looked around, as I have some interest in these,
and the situation is not good, LED or no. The problem is that the
resolution on the cheaper ones is dire. Anything below 1000 pixels
vertically will not show much detail, and even that is considerably
below the resolution of even a mid-range amateur camera nowadays.
For example, the Epson EB-S02H is 800x600. Sorry :-(
