I've been a paper scrapper forever, and I started digi scrapping in May. I think digi is still much cheaper. I could easily spend over $100 on one visit to the scrapbook store. I've only spent about that much in total on digi scrapping (I did already have Photoshop, but whatever program you get would just be a one time investment, and well worth it.)
I haven't paper scrapped since before I went to Disney in Sept. I've just been really busy or sick, but I definitely need to get back to it. Even though I love digi scrapping, and have been doing a LOT of LOs, I still feel like a paper scrapper at heart. I love them both for different reasons.
