According to these guys http://www.bestcashcow.com/savings.html there aren't many offers greater than your 5.32% and all seem to have some strings attached in the form of higher than normal minimums or teaser rates.
Seems like somebody posts this question about every week There are lots of choices...depends....seems like a lot of folks are using Eloan right now...I use it to link my main bank account that I deposit checks....can only link 1 bank account per eloan account, though...there is a lot more discussion on fat wallet finance forums also...
It seems that Eloan required a minimum of $5000 in order to get 5.38%. UFB and and Emigrant direct has no minimum startup and no additional fees. UFB also offer an ATM Card.
