I have to respectfully disagree here. I would order a 4 quart flask from Northern brewer. I slummed it for quite a while with starters, but it's really nice to be able to cook, cool, and ferment in the same vessel. Don't forget the fermcap!
It's not like I haven't tried a flask. But I found them fussy about volumes and fragile. I decided that a jug worked better for me.
