Slide duplicators digital cameras and parts

What do you all think of the slide duplicators that attach the lens of your digital camera? I have a dimage A2 and was thinking of getting one of these to do some slides and for some negatives we have. I've seen this Opteka copier and a very similar Bower and wondered if anyone can say good or bad about them. Also in the parts picture I was wondering if anyone know where I could buy that carrier that holds the negatives. Or if you have one lying around you'd like to sell??

Thank You

It really depends on the kind of image quality you're looking for. I can't recall seeing any samples from a digital slide duplicator. But I can't imagine they come anywhere near the quality of a good film scanner. And since the price of a good film scanner is now below $1000, that's what I would go for. I guess it depends on your budget and expectations.

I haven't heard very good things about them - if you're looking for a high quality image anyway. I suppose they would be quick and easy for a quick record or catalog of your slides or negs, but they probably won't make a good print.
