I have the Hario Mini which is the smaller version of the Hario Skerton. It has worked great for me. I only use it when I travel now. That said, I've tried no other manual burr grinders, so...
I've only heard the Roxanne in their new line up. I still enjoy it, but there are other options. Too many options to get a handle on what's better than what.
The Andrameda does seem to get universal praise.
