I would definitely start out with a B.V. since it would be much easier and cheaper to set up, and less hassle/paperwork when tax time comes.
Then, when revenues justify the investment, I'd set it all up properly in the US with the help of a good attorney and/or accountant.
An important point here is that as a B.V. you would be governed under Dutch law if someone sued you. This should be disclosed in your terms and conditions as it will be considered unfair trade practice otherwise. If you feel you don't want to hire an expensive lawyer, I think the KvK has an export desk where they can help with these kinds of questions.
But it all depends on what kind of startup you have - if you have already validated the idea and have some investor/savings money I would hop on a plane and get it sorted there straight away :)
