best sweep out + sweep in savings account?

i know hdfc has moneymaximizer category of accounts.

but apart from that, which other banks have a good facility for this?

for those who don't know: sweep out is when excess amount in your savings account is automatically moved to an FD. and sweep in is when only the required amount of money from this FD is automatically deposited in savings account in the event of a shortfall. it allows you to earn a better interest while maintaining liquidity.
