UFBDirect offers 3.30% and a $25 bonus if you make a $200 deposit by May 31st. However you cannot make ACH transfers (web transfers) so you have to have another account which allows you to "push" and "pull" money out of that account. Because of that I cannot recommend this account and I won't use it myself.
A run down of the ones I use:
ING Direct 3.00% 5/5 dbfn rating
VirtualBank 3.05% 4/5 dbfn rating
Emigrant Direct 3.25% 2/5 dbfn rating
