Hey Sarah,
You might also want to check out sites to have your pages printed from. I have mine printed at whcc and it ends up being about $3.60/page and that includes shipping. For me that's a lot easier than printing them myself. I just started scrapping digitally in January (I use PS7 too). I get some pages done really fast and others might take a couple of hours (plus I still find I'll go back and tweek things a couple of days later). Scrapping digitally is definitely less messy for me and and since I don't have to glue anything I'm a lot happier.

Another benefit to it is definitely the fact that you can "undo" things you aren't happy with. I was a little leery about making the switch too, but now I'm so happy I did. Good luck!
Sandy
