in need of a scanner.

Hello to all. I'm looking for a scanner, just a scanner but with software that will do the following

1. Scan a document and convert it into pdf 2 scan a document and convert into n image pdf if necessary.
2. Ability to save the pdf to my hard drive or iCloud or where ever.

Of corse the software and scanner have to be about 90 percent accessible with mac and window. I should add this cannot be a printer scanner thing. I already have one but I can't carry it everyware, it's heavy. Lol!

Take care to all and any recommendations would be good. I'm looking for one under $100.
