About embroidery machines, I only have experience with Bernina machines, but I would definately get one with 2 hoops for the things you mentioned, because you will want to do so much more than what you originally wanted. Generally they will stitch out a design up to 5 X 7 and 4 X 4 sizes. Some machines come with larger hoops (mine does).
The Bernina Deco 340 is a nice machine. I had one for a year then upgraded. I out grew it so fast.
I also would recommend getting one that you can use a USB stick to transfer your designs from your pc to your machine. That way you avoid the extra cost of a magic box (or similar devise) to transfer and the costly design cards.
Keep in mind, you will need stabilizers (recommended espically for emb machines) and that isn't cheap! Then there's the threads...
I'm not trying to chase you away from embroidering, just wanted you to know a little about it. No one told me these things when I first got into embroidery.
