I closed with National Bank of Kansas City about three weeks ago.  The BEST lender I have ever dealt with, and my real estate agent said the same thing (he's been an agent for 20+ years).  
I worked with Tim Lander, and would recommend him.  He was prompt at returning calls/emails/documents to myself and my agent within hours.  He definitely went above and beyond.  He blew the other mortgage rates out of the water.  PM me with your e-mail address, and I can pass along details of the loan.
