Thank you all so much for taking the time to reply. After looking at everything I could about the machines I finally decided to get the PC420. I am so excited....it's supposed to arrive tomorrow! I also have some new material coming tomorrow that I ordered from Joann's. There was a pattern on Joann's website called Zesty Tote (If I'm remembering correctly) and I want to try and make that. Unfortunately they didn't have that material online and I didn't see it in the store either but I already have lots of material to choose from.
Also, I know the throat isn't as large as it should be but I want to try to make a smallish quilt to hang on my wall. Are there any good books, patterns or websites for beginner's that you would recommend. I will definitely be trying to gather as much information as possible from this site and am very grateful for any knowledge or wisdom you can give.
