Who do you use for your business bank account?

I was considering using Natwest, but I have found them slow and unhelpful - if they aren't going to make every effort to get your custom in the first place, then what will they be like when they have your custom and you need assistance?

Other options are Abbey National - who offer fee free banking, but require a deposit at the start, or Alliance and Leister (but they charge a fee if you have low activity on your account).

I'm looking for a fee free bank account ideally - the account I have now is OK, but I don't use most of the services offered, and I don't see the point of paying for my banking when all I want is a place for my money to sit :-p
