Another vote for the MSR (I have a Dromolite) with the spigot. I've been purposefully mistreating it, filled to the brim and resides in my car for constant use, and haven't had a problem as of yet. Hung on the back of the car to use as a faucet for the kids washing up for a car camping trip worked well too. Keep the cap on the spigot though, it didn't seem to leak even with the valve on (kids apparently played with it and turned the valve to "on").
