Where to download intraday historical stock data?

Question

Hi. I am looking for historical, intraday stock data. More important than anything else, I would like the smallest interval possible. 5 minute intervals are okay, 1 minute is better, 15 seconds is awesome. I'd like to have the historical intraday data for at least 100 different stocks on NASDAQ, dating back at least 5 years.

I don't care how much space the data takes up, I don't care if I have to shell out a hundred bucks for the data. Does anyone know of any way to obtain this data?

Thanks!

If you open a stock acct at the right brokerage, they may have limited historical quotes of intraday data.
