[quote=rehess]...My best scanner, which I have used to scan over 2500 slides over the years, is a Nikon LS-2000, which I bought refurbished on eBay... but Nikon no longer makes scanners, and [u]this model requires that I keep a Win XQ computer going because of hardware and software compatibility issues[/b][/quote]
To use your Nikon scanner with a more modern computer, you just need to update the software. A more recent version of Silverfast AI or get a copy of Vuescan. Silverfast can actually do a better job than the original software provided with the Nikon scanners. Vuescan is simpler and cheaper, but works pretty well, too.

I have a Nikon Coolscan 4000 ED (LS4000) that I bought new around 1999 or 2000. It cost about over $2000 at that time, if I recall correctly. Most recently I used it with Vuescan (on a Windows 7, 64 bit computer).
A key reason I got the LS4000 was that it can optionally be fitted with an accessory slide feeder (SF-200, which was about $400 of my original cost). This feeder will hold up to 40 mounted slides and feed them automatically. Since highest resolution scans take quite a while (and end up as 130MB 16 bit TIFFs), this comes in very handy with any volume of slides to scan. I just set it up and let it run overnight. In the morning I have a folder full of scans.
The Nikon and some other dedicated film scanners can automatically handle a film strip automatically, too. In fact, if a roll of film is uncut, it can automatically process the entire roll, too (not that I have any uncut rolls... don't imagine many people do).
Flat bed scanners might work okay, but a dedicated film scanner can be faster and offers the highest quality. I'd look at a used Nikon, Minolta or new Plustek, Pacific Imaging film scanner, if you're concerned about high quality. I made prints up to 16x24" from 35mm slide scans made with the Nikon LS-4000 (4000 ppi).
Many of the "cheap" film scanners are just a waste of money... producing 5 to 15MB files that are only good for small prints (compared to as much as 130MB from a 4000 ppi Nikon scanner).
