I am looking for a Thermos for coffee for ice fishing this year. Can a good one be had for $30 or less? I'm not really expecting something to keep hot for 12 hours or more since my outings would be shorter than that. I don't want to get something that is going to be luke warm after 1-2 hours though. Any recommendations? I was initially looking at these on Amazon.
