Coffee Grinder?

The other topic about coffee brought this question to mind...

We use a french press while camping.

I'm looking for a coffee grinder that makes medium to largish grounds so the filter in the french press does a better job. We have been buying the pre-ground coffee for our trips, but don't like the grounds in our cups of coffee.

I'm not sure if we should have a small (non-electric) one to bring with us and grind new beans every day - or - one to leave at home and bring a jar of grounds with us.

Any suggestions?
