Source for 1- or 15-Minute Data Other Than eSignal?

["Damien" <damienb4l@xxxx>]

AmiBroker's website says that the Standard Edition can do 1-, 5-, 
15-minute, hourly charting/backtesting/scanning but does not 
require a real-time data subscription (such as eSignal). 

It's my understanding that QP2, Yahoo, etc. provide just 
Open/Close/High/Low (and a couple other numbers in the case of 
QP2).

Where can I get 1- or 15-minute data (other than from eSignal)?

Thanks,

Damien
