What is a good brand that preferably goes to 12mm (12mm is a essential size, sets that only go to 11mm confuse me). I am in the market for a new set! 
Pratts and crapsman only go to 11mm in the sets
I've always had good performance out of Pratt-Read drivers. Never used their nut drivers, but I'd say - if they're anything like their screwdrivers - they'd be a good bet.

That exact set can be had from Harry J. Epsteins for $20.00

The Proto J1212MND 12 piece set goes up to 14mm. They also have the Duratek handles. I have the same set, but with the old style handles and really like them.
If you like using nut drivers, and you know you'll use a particular non-included size regularly, why not buy the set plus the singles?
I can't fault my socket set for not including the 32mm I needed for the suspension overhaul I did last year, or my screwdriver set for not having the 5 wing microtip for the iPhone I repaired.

I just did the same, the metric only go up to 11mm and the SAE go to 1/2 ". I use them a lot on hose clamps and starting nuts on small engines mostly but must never have needed a 12mm or larger!I have a craftsman set... And never noticed they only went up to 11mm until I just went out and looked. I don't use them too often.

I own several sets of nutdrivers (klein,craftsman)
I never use them anymore. They take up too much space on my cart and there is something that works better.
What I now use is this, has a super ergonomic tacky grip

Plus you can get the other shanks that hold 1/4" bits of all kinds, I use hex,torx daily and this system works awesome. I still use regular drivers for phillips and flat, but for other bits and when a nut driver is called for you cannot beat the snap ratcheting with interchangeable shanks.
