You sure are doing your due diligence and I applaud you for your efforts.
Good lending comes from good experiences with individuals - not companies. However, you do want to be careful to stay with the tried and true - in these tumultuous times. Your own bank is a good starting point, but if you don't get the best rate - its time to start the interview process.
Just remember, that there will be times where you open your loan with one company, and by the time the ink is dry on your closing documents your loan will have been sold to another company. Try not to lay faith in a name or an individual. Get everything in writing - that will be your gauge because that is what you have to live with for the next 5 to 30 years!
Good luck to you - I know you will do well. You're already off to a good start!!!
