Liferea looked perfect as it syncs with Reader but no longer can auth with google.
Thunderbird does a decent job even though it's not mentioned. Like all the other solutions I've tried it doesn't download the target page, only the text in the RSS itself. No pics or other attachments.
Usage:
- export RSS list from Reader
- import into Thunderbird
- when going offline it automagically updates feed list
- read offline later; if I want to follow links or comment on something I email the article to myself using the Thunderbird Forward menu button and read it later.
Works fine.
Thunderbird is turning out to be a pretty good solution for folks too cheap/frugal to buy a mobile data connection.
