Visiting USA: PAYG data plan?

I will be visiting the USA for a couple of weeks in late summer.

I am now looking for a pay-as-you-go (a.k.a. "prepaid") SIM card that offers me a certain amount of data that I can use. I am guessing that I will use up to 500 MB over the air.

Do you have any suggestions about a reliable PAYG data plan?
Where could I find more information? The AT&T and Sprint websites are a real horror to navigate through. :)
