There is an easy way to tell if the lens your dealer is pushing
is worth-while:  take two identical slides down to the store,
ask the dealer to set up two projectors side by side, one with
an Ektanar and one with the "RAYNOX", and compare images.
If one looks better than the other, you've probably answered the
question (though swapping lenses will make the answer more definite).
If you can't tell the difference, you may also have answered your
question.  If the dealer won't do it, you've definitely answered the question.

But if you're in the market for a slide projector, I urge you to
consider the Leitz Pradovit RT-300.  The New York discount houses
seem to be offering them at a variety of prices, mostly around $300.
You probably want the 90mm f/2.5 Colorplan-CF lens that comes with it;
the CF stands for "curved field" to match the normal curvature of
cardboard- (or plastic-) mounted slides.  The Leitz takes Carousel trays
and the Kodak stack loader and slide clips.

The difference in image quality between the Leitz and the Kodak I
compared it to is immediately obvious to the most casual observer.
