I like my final prints in 24x30 cm.
My flatbed scanner is A4 size (correct lenght, but shorter width), so if I want to post a photo, I have to make a smaller copy also.

I wonder if it's worthwhile to purchase one of the used, inexpensive (circa US$50) negative scanners that shows up on Ebay from time to time, just for B&W Internet postings.
(for color I have an Coopix 2000, used mostly at parties, etc)

Any suggestions or the really cheap ones are useless?

Thanks,
