Have you tried Holland's Meat Market and Cafe'?
They are located over off of New Sugar creek and hwy 30. I've been a few times and liked the quality a lot. I tend to do Dierberghs a lot though still because we are friends of the family owners. Always been satisfied with them.
As far as briskets go, I don't do enough of them to give you a good answer on where to find the best.
