manuals in pdf (resolution, compression)

I have a lot of manuals I want to scan and am trying to decide upon the best format. I'd like some opinions on the following scans of a 128-page Franklin AceWriter manual. On the low end is a pdf of bitmap images. It's hideous, but only 3.5 MB. The high end is a 40 MB pdf of jpeg images. This one's easy on the eyes, but is an awfully large download and I'm wondering if it might not print as nicely as the bitmap. In the middle is a pdf of compressed jpegs at 15 MB. This looks good to my eyes, I just wonder about using compressed jpegs for archiving... <www.applefritter.com/temp/acewriter_lo.pdf> (3.5 MB) <www.applefritter.com/temp/acewriter_med.pdf> (15 MB) <www.applefritter.com/temp/acewriter_hi.pdf> (40 MB) (Disregard the incorrect ordering of the pages.) Thoughts? Which of the three would you most want to download? Tom Applefritter www.applefritter.com
