I want to get a film scanner to capture 8"x10" positive to PC. Could you give me some advices regarding:

1. What is the file size (best quality) with a scanning resolution of 6400x9600 dpi?

2. What is the quality of this file? I mean if I send this file to photo printing lab to print a 16"x20" photo. What is the quality of this photo? Of course, you may ask why not send the film directly for a print.

3. Which scanner do you suggest? Epson? Nikkon? Drum scanner?

4. How much should I pay for a good quality scanner?

Thanks a lot.
