I have been using PSE for a few years. Photoshop Elements 12 by Adobe. There is a free download on the Adobe site. There is a small learning curve, but once you know the basics, you can take a years hiatus and still navigate your way around. There are tons of places to find free or nearly free digital supplies. Personally, I like Designer Digitals and Oscraps the best. The finished pages seem to better reflect the paper scrapping that I fell in love with originally.
Good Luck- I certainly understand the space issue. I wait now and print my pages in 11x11 books with Photobook America and wait until they offer coupons!
