Here's an example of the standard process: http://www.hsbc.co.uk/1/2/switching-to-hsbc
If a CU wants my business, they should have a branch that's open till 8 or 9pm, open saturday and sunday, and have plenty of ATMs throughout town. That's a start, then they can have at least everything WF offers, such as linked credit and home equity accts. They should innovate, not lag behind.
As for the number of ATMs, both credit unions that I belong to are part of the sum network (free reciprocal ATM access) and actually reimburse me for fees that off network ATMs might charge.
After years of getting slammed by big banks with excessive fees when cash was tight and balance ran low, I came to appreciate using an institution whose goal is not to profit off of me however they can.
The scariest part was, after a couple months and no spending, the bank said to close my account I had to write a check to myself for the exact balance in my account. Once cashed, and the account hit $0, it would close automatically. I was terrified of overdrafting or undershooting it by 1 cent or something.
FWIW I went to Chase Bank. I'm not happy, I'm not sad. Banking is as exciting as a loaf of bread. The less I interact with a bank and the humans at a bank, the happier I am.
