If you're having any problems with Google Reader, try http://kindlefeeder.com/
The free version limits you to 12 feed sources but the interface is excellent. The paid version ($20 a year) has no feed source limits and you can set it to automatically email your feeds each day. They have something like 1000 feeds ready to be selected or you can add your own.
I use both Kindlefeeder and Google Reader but I'm coming to prefer Kindlefeeder.
