All,

I've been in the UK since mid January and been commuting by train since (btw: I will add to the 'commuting by train' thread shortly). I've spent months trying to find a good coffee shop and nothing. Yes, there are the Starbuck's, the Nero's and the few mom and pop's... but nothing that I would classify as good enough that I would return to.

After all of that, I broke down and bought my own grinder and espresso kit. Well I should say I was told by my wife to stort out the coffee situation or else (she was serious!).

Now i'm bringing my favorite drink to work in the morning in some thermos that started leaking after day four of use.

Here's my critria and hoping that someone out there has been there/done that:
-500 to 600 ml
-will not leak, ever
-will stand up to being in my briefcase for the ride in the morning
-ideally, if it doesn't have the screw on cup/lid that would be great, but not a deal breaker
-will not leak!!!!

Anyone have any suggestions?
