Take a look at the Leopold 210TP over on elitekeyboards. I've been thinking about getting one of those. Nice and sleek with a tight bezel.
If you want programmability, look into a mode 4 G80-3700 (MX 3700).
If you want to spend money, EK also has the Topre 23U.
And then there's the Filco one, though unless you care about matching it to a Filco keyboard, I don't see a reason to get anymore with the introduction of the Leopold, which just looks better all around (though I have yet to compare the two physically).
