The uKeg Pressurized Growler looks like the best invention since sliced bread. These days I'm going more for quality than quantity so a small growler in the fridge for weekends fits my lifestyle perfectly.

Although not quite available yet, I'm going to keep my eye on this.
The Kickstarter funding ends Sunday, Dec 7th (no affiliation, just a beer drinker) and there is a website with video to check out. Looks like the Growler Werks uKeg will be available in time for next summer.
