Go to the place above,a very old line lumberyard. They're located in the north end of Rochester, Mi. Carry a number of cabinet lines plus fixtures etc. Very nice stuff but more expensive then big box stores.
or
Find a independent Craftmaid dealer. That is a middle line supplier. I did a huge kitcher with their stuff two homes ago and their upper line is pretty good stuff.

Basically boils down to what you want to spend, sort of Cigarette vs. Bayliner.
