well if it was me, i'd go to london drugs and pay them to do it. they'll give you a good high quality scan. it probably cost 150 bucks, but its better than sitting at home and taking an entire DAY to do it.
I have the same issue - many slides - wondering what to do with them. I have read a bit, and will probably settle on the 4870. I still use a SLR camera, and plan to only develop (but not print) film that I have shot. This way I can scan the negatives, and print as required.
This will be a slow project, so time is not too much of an issue. This will also give me a chance to throw out slides I am not happy with.
Two years ago I was in the same situation. I tried a flat bed scanner with a slide adapter, but was not pleased with the results. I bought a Minolta Dimage II and I am very pleased with it. It was $450 at the time and came with PhotoShop Elements software. Scanning is VERY labour intensive. It is very important to dust or clean finger prints from the slide or negative before scanning. Software can repair scratches and other damage to old negatives but again also very labour intensive. I have scanner a couple thousand slides and negatives over the last couple of years. I am still rescuing old negatives and slides family and friends.
A side note:
I recommened the Epson PictureMate 4X6 photo printer cost 40 cents a photo. If I need a larger print I take my digital files to the photo Lab.
With your own slide scanner, software, and printer you are in total control of your end product
Just am two cents
