I love Discover because they were the first to give me a credit card after I graduated from college. They've been very responsive any time I had an issue. And I really like not paying for things I order from Amazon because I use the Discover cash back rewards for that.
However, for this thread I'll just mention Greater Iowa Credit Union's checking account that pays 3.04%. Of course there are requirements like a direct deposit, some bill pays and debit card usage. But, we were doing all of those when we had a regular checking account there, so just switching the type of account gave us a higher rate.
