Fundraising - Poster Question

I'm not familiar with either one, checked the sites and I can't tell the difference. I'm really trying to get away from paying others for something I can do myself. I fully understand and appreciate using the fundraising operations (cards come to mind) and know they can be very, very beneficial.

It's a Mac application for generating image files up to 20x30, but I'm sure there's something similar for Windows. Do your own poster, generate a print file, take it to Staples/whatever, and print your copies there. Now, I haven't done posters specifically for fund raising, but I have for the weight room with the schedule and images and quotes and such.
