I've been using BitMe.com to sweep funds to my bank account because they charge the lowest US ACH fee of $0.25
Last Friday I put in a withdrawal request.  The funds were in my bank account Monday morning.  That's 1 business day.

Way to go BitMe.com!  I will be using your services in the future!  Only thing that could make it better is if you accepted MtGox codes instead of Aurum Xchange codes for deposit.
