First post, long time Das Keyboard user.
Anyway, any blank keyboard like the optionally blank das keyboard and unicomp boards will work fine especially because nubs or curved keys will work without movement. For me it's the most elegant solution... but learning those key setups is a pain.
I should look into some other key arrangement, but I would need to read a lot about it first to figure out which ones I care about. Key placement for various shortcuts is very important to me.
Edit, I tried dvorak and one thing I liked about it is I could guess where keys were. Physically intuitive movements got me the letter I wanted on more than one key if I recall. It was a very interesting, almost a psychic feeling, but common commands like copy/paste/lock/etc were all re-arranged in ways that broke my flow and reduced productivity. Colemak looks REALLY good because it doesn't move 2 of the 3 listed keys and the one that is moved isn't moved enough for me to care about.
