banking while full-timing

[rec]

My husband and I are getting ready for a full-time lifestyle -- but we're curious about which banks people use while traveling across the country. We need a bank that gives us free (or inexpensive ATM usage) throughout a broad network so that we can make deposits and occasionally withdraw some cash (I found one bank that has no ATM fees on their end and re-imburse you for 2 of the other bank's transaction fees a month). I would prefer someplace that actually had walk-in branches around the country, but that might be hard to find. We need both business and personal accounts with online billpay -- and if we could get free banking, that would always be a bonus. Any suggestions from the full-timers out there? Thanks!
