Both paces Loren mentioned are 44 cents per frame (for 35mm negs) at 2000 ppi. The first also offers 3000 ppi for 84 cents and the second place 4000 ppi for 74 cents.

I would never consider doing more than a very small amount of images on a flat bed scanner, let alone trying to use slide adapters.

The prices above are very tempting if one is considering buying a Nikon or similar scanner for a single job. I have a lot of negatives, but once they've been scanned, the equipment will go unused. For anyone lucky enough to be able to borrow a scanner the choice becomes a little more difficult.

I'd hate to spend the time on it myself, but I'd also hate to blow US$1000 and possibly end up with something I'm not 110% satisfied with.

Please update this thread with any personal experiences with the scanning services as well as DIY.
