In any case the best results are always obtained from drum scanners .. and such facilities do exist in the more professional photography studios in india.
In fact , from the regular photo shops(Delhi) i've had scanning done at much higher resolutions than the 640x... You just have to ask for it ( and maybe also have to be a regular customer).
Buying a costly scanner for the average individual(s) use in india is not exactly practical unless you can find enough of your own images to digitize (or perhaps you might want to extend this service at a cost in your neighborhood ) - maybe you could even think of getting a good macro lens and "shoot" the prints instead of scanning.... its just a thought.
