Make sure you get the FDIC account. GM and other companies have money market accounts backed by the company. I wouldn't want to be an unsecured creditor of GM. I think they are doomed and will go under when the UAW drives them into the ground. I doubt that the UAW learned anything from the steel workers' union.
Does anyone have experience with GMAC bank. They are currently paying 5.3% on a MM account with check writing priviledges.
