Why would you want to take a risk and have a relationship with a smaller bank in your community? It might not be as big a risk as you think, especially if the banker probably knows you.
Community banks with one or just a few locations may also:
1) offer higher yields and high interest checking accounts (Use checkingfinder.com to locate.)
2) have more competitive rates on loans (Check http://www.bankrate.com)
3) actually base your rate for a loan on how they know you and the quaity of your relationship, in addition to your credit report.
