Google finance, albeit the API isn't as developed as you might expect but most everything you need is there.
You can use the Yahoo CSV file generator: http://ichart.finance.yahoo.com/table.csv?s=YHOO&a=00...

This is an example for Yahoo quotes from Jan 1 2012 until April 1 2012. So exchange YHOO for the ticker you want. And then: a = start month (always dubble digit and 1 less then month number, so april is 03, dec is 11, etc) b = start day (no 0 in front if < 10) c = start year d = end month (always dubble digit and 1 less then month number, so april is 03, dec is 11, etc) e = end day (no 0 in front if < 10) f = end year

Thanks for the tip, and the primer

Was hoping for something a little more directly consumable, but a CSV isn't the worst thing in the world.
