Which Banks To Link To Reward Checking?

I would rate Alliant Credit Union as an excellent choice for a 'hub' bank/cu to link to other accounts such as Reward Checking.  Alliant continues to pay 1.50% on its checking account, has no limit on the number of banks/cus which can be set up for ACH, and has the fastest ACH transfers around.  ACH transfers initiated before noon Chicago time are completed that day.  Many other banks/cus take 3 days to complete a transfer.

I did a one-time ACH transfer from Chase to another account last week for the first time and it went fine, with no fees.  It took 2 days to post into the receiving account. The Chase interface offers recurring transfers; I haven't tried that yet, but I'd guess it would work the same way. The set-up for linking the receiving account was very standard (using test deposits) and presented no issues.
