So, i agree that the page is a little busy. Maybe I'm dense, but the "Cash to Save" was ambiguous and couldn't decide if you meant "The end amount of cash I'd like to have after X months" or "How much I have now that I can move to this account".
On the "Learn More" page after clicking a bank, the slider occasionally mis-renders. (The handle will render under the textbox which requests my deposit amount.) This is usually if I max out the Cash slider on the first step. (OS X 10.6.8, Chrome 14)
This seems pretty straight-forward to me. And pretty helpful. I think you're moving in the right direction.
