My advice would be to RENT a 35mm film scanner. After you practice for awile the scanning will not be that bad.

With my CS 4000 I can scan a slide in about 1 minute using the fastest setting. Realistic time is about 1.5 minutes, slide to slide. At that rate you could do 250 slides in about 6 or 7 hours. Not that big of a deal.

A noncompressed slide scanned at 4000 dpi will produce a file of around 67mb so you will need to have hardrive space and then do DVD backups.

I have not had good luck scanning with Kodachrome slide film for some reason. My Provia scans awesomely but the "25" and "64" have had issues. I am sure that it is just me though.

If you can not find anyone to rent you a unit I would try Ebay and pick up a used one for a song.
