Recommendations for a Good Shaving Mug?

Hi All,

So as I'm starting to explore the world of traditional wet shaving with my Edwin Jagger DE89L, I started realizing I might need a vessel that's better to build lather in.

So if I can ask all the Shave Nook veterans:

* What's a Good Shaving Mug to use?

(FYI: I like to build Lather in a Mug via a Shave Cream)

I currently am using an old Coffee Mug and it "works," but it's kinda tight for my fingers and the Duke Brush to build lather.

Also, I read quite a few threads about Scuttle vs. Bowl vs. Mug, and I think I'm not quite ready to try a Scuttle yet.

* But is there a big difference between a good Shaving Mug vs. Bowl? (is it mainly space concerns?)

Thanks for the help!
