tick data

Tick Data for which asset class? There are brokers and
data providers that offer free trials for 7-30 days,
most of them allow you to download data.... Otherwise
the best data I have come across are from CSI:

Check

Hello, 

I am wondering if there is some source which has
more than 2 years'
tick-by-tick data for free or cheap.

thanks,

Ed
