529 Plan

I'm looking to open a 529 for my daughter but I'm not really sure how to choose the best one since it's pretty new to me. I'm a Texas resident so there would be no state income tax deduction available and I'm not interested in a prepaid tuition plan.

Since I do most of my investing with Vanguard I'm just considering signing up for the Vanguard 529 Plan which happens to be based in Nevada. I haven't done too much shopping around but my assumption is that the variety of funds available and expense ratio will be just as good or better with Vanguard than most of the other options out there.

Has anyone else with a similar situation found a better 529 plan? Is there something else I should be taking into consideration when choosing a 529?

Any help would be appreciated. Thanks.
