The Minolta DiMAGE Scan Elite 5400 II was considered to be about the best quality / price combination when they were made. Unfortunately no one took over manufacture of them when Monolta quit the imaging market. They do appear on
Ebay from time to time in mint condition as most of them have only been used to archive old slide collections and then are no longer needed.
Nikon still make reasonable ones for similar money (£500). More versatile but less good (only a little) is the Epson Perfection v750 and it's slightly cheaper and (again, slightly) less good sibling the v700.
All these machines will extract the maximum from your slides with good dust reduction. Better than this will be the domain or your local graphics bureau. There are then a variety of cheaper flat bed and dedicated film scanners that will do a less good job for way less money. You pays your money.....
Finally slide scanning is slow and getting good results requires quite a lot of fiddling. I don't use Fuji, but controlling contrast with Kodachrome is a nightmare. If your lab offers you scan to cd for a few quid when processing your film, then it takes a lot of beating. Alternatively if you want digital images from the pictures you are taking today, then buy a digital camera which will capture better images at every price point than the film / scanner route. (The exception is where you have a huge inventory of non legacy lens that are critical to your work or a back catalogue that is worth preserving on mass. Having 100 or so slides copied will be cheaper via a bureau.)
