A lot of people have asked this question about scanning old 35mm slides and it seems that the Epson 4490 has been recommended. I have Vista and it appears this scanner is not compatible with my operating system. The Nikon Coolscan-V ED was also recommended to me and it is Vista compatible, is this a better scanner? Obviously I want good quality, ease of use, and an affordable scanner. Do you have any advice for me?

I Have close to 900 35mm slides that need to be scanned and converted to a digital format for my Mac I would prefer .jpg’s but any digital format will work . How can I go about accomplishing this?
I currently have a Brother MFC420 / flat bed scanner but I am not sure it is the right tool for the job.
