I have Digital Scrapbook Artist, PSE6 (photoshop elements 6), and PSCS2 (the big mama photoshop version).
While Digital Scrapbook Artist(DSA) was cheap, it took a lot of my computers RAM and so it ran fairly slow. A few months later I saw PSE6 for only $50 so I grabbed it. It ran SOOO fast in comparison to DSA. It also has SOOOO many capabilties. For the money, I dont think you can beat PSE. You can use it for so many things...scrapbooking, photoediting, photo organization, etc. I think PSE is fairly user friendly and there are SOOO many tutorials on the web to help. PSCS was given to me and it has more features than PSE obviously, but for the $$ PSE can't be beat in my opinion. If I had to do it over again, I would purchase only PSE if I were on a budget.
