Best Cylinder Head Porting Shop/Vendor- Your Experiences w/Results

I've been trying to do some research on who does the best porting work (I'm talking about shops or vendors or individuals that offer it as a service). Thought it might be nice to have a compilation of people's experiences with various porting companies and vendors.
