There are a bunch of SharePoint presentations that can be downloaded for free from the member’s area at Critical Path Training site. Check it out here:

The presentations currently there are from me, Andrew Connell, Ted Pattison, and Scot Hillier. More will be added after each conference. I would suggest signing up for the member’s area (did I mention it was free :-)) and taking advantage of it.
