I subscribe to the daily newsletter from www.scrapgirls.com
and more times than not they have sort of tutorial in the newletter. It's at the bottom, most of the time they are for PS or PSE, but I saw one for PSP the other day. In todays letter they were advertising for some online tuts. They also have a "how I did that" section in the newsletter, where someone posts their lo, and then tells you how they did a portion of it.
