High Interest Investment

What is one of the best money market checking/savings accounts with the highest interest yield?

I currently bank of Bank of America. I am disappointed in their low interest rates and am thinking of switching to a brokerage or mutual fund firm that handles checking and savings accounts as well as retirement funds. Can anyone recommend one that yields a decent rate of return with low fees? I'm also thinking of possibly linking a Capital One 5% money market savings account to my existing accounts. Does that make sense to do?

1. I was considering ING Direct, CapitalOne and HSBC online account. I am going with CapitalOne because I have a company credit card with them and love their service so far so I am looking to build a deeper relationship with them. Getting more than 5.5% in the US is hard on these kinds of accounts but atleast that is better than the pittance most banks give. Check out http://www.bankrate.com for rate comparisons as well as all the fine print and good luck.
2. Banks are coming out with promo rates constantly, so it's hard to say. ING always tends to be very competitive.
