I need to change to digital projection, I occasionally give talks to

difficult to get hold of the slide film so last year bought a DSLR

I make no claims as to how good they are (and I don't know what you
consider cheap) but this might be worth a look?

This one is around £650 but there are some cheaper alternatives available
