There are lots of other free tutorials on the net but if you really want a tutorial from this site and this site alone i would suggest buying points that way you support the people who are making those tutorials.
I think when you download a free tutorial it downloads from the same host as from where this site is hosted so if there are alot of people online bandwidth get's pretty low.
And when you download a payed for tutorial you download from a seperate server which is faster.
But that's just my guess:p
