I've done my checking with Wachovia for several years now (formerly a Crown Checking account and now free checking). Their web interface for managing your savings and checking accounts is quite nice, and integrates nicely with BillPay and investments (if you had an IRA or stock portfolio through Wachovia).

As far as I know, free checking entails no account fees, but you do have to purchase your own checks I didn't mind, as the checks from my original Crown Checking account were still usable. When the time comes to purchase new checks, I'll likely do so through Costco or a third-party, as Wachovia's checkbook prices are a tad high.

A huge plus for this product is Wachovia's online BillPay application. It's not just useful for paying utility and credit card bills with registered businesses. BillPay works great for mailing a check to anyone (friends, landlord, etc.) for free - Wachovia even covers the postage costs.

Perhaps one of the only negatives that comes to mind is the nonexistent interest rate, which doesn't stack up well against other banks that are offering free high-yield checking accounts.
