Intra-Day data Sources

[Robert Cavaleri <rcavaler@xxxxxxxxxxxxx>]

I am looking for an inexpensive solution to find intra-day data that can
be downloaded end of day for systems development testing (I decided I do
not need  real-time streaming data just yet). I have been using free end
of day data from 'the big easy investor' which has been great, but my
most recent ideas require intra-day data testing .
     Although I have never used HistoryBank.com before, it seems as
though it will only let me download 3 months of intra-day data from the
current day. Is that supposed to fill in the gap between what is on the
current HistoryBank Data CD? If so that kind of leaves me high and dry
because I no longer own the HistoryBank CD.  (besides that, I thought
the HB cdrom only had end of day data on it anyway).
     Somebody once mentioned to me that yahoo had a free on-line source
for data. If someone knows where that source is , could you please post
a link? I am curious if perhaps their data might be intra-day, but I'm
guessing it is probably only end of day. Other than those two
possibilities, I have not come across another on-line solution that
provides a cost-effective solution for non-streaming intra-day tick
data. Anybody have any suggestions?

Many thanks,

robert
