historical intra-day data

I've searched but couldn't find historical intraday data for US equities.

Does anyone know of a source for say, 1,2,5-minute bars for 1-2-3 years?

 

People have asked this before, and I believe one source they listed was the tickdata web site. Do a search on tick data in elite trader and see what you find.

 

good deal, thanks.

they have 1-minute data, but I can convert that to other intervals
