We have a SunTrust account so we can pay our dues on monthly basis by DD rather than in a lump sum on January.
For us it is far easier as we have to pay for Xmas in January and one of our cars road tax is due then as well (and is the one that has the expensive road tax too

)
It does cost in that we get about 2.5 cents less than the bank rate on our exchanges but also we can pick and choose when we transfer money so more when is good to cover the bad times. I use XE.com as my fx transfer agent. There is no fee per transfer and the rates are fairly good.
I opened a halifax account as they only charge £9.50 for doing a online transfer to international accounts but their rates were really bad - even less than using paypal and that didn't take account to the fee which would be extra.
