I don't think you need to worry about digitizing. The software is expensive, and there are lots of designs available.
My Bernina 180E stitching area is 5 X 7, and thats about as large as I want for quilt blocks.
As far as stitching a design and moving it 4 times, will you use it enough to make it worh the $$$?
So many features on embroidery machines never get used or used so seldom its not worth the extra $$$.
Don't forget after you buy your machine, you will need to purchase embroidery thread, you will need 30-40 different colors, you can pick up several each time you do a design,bobbin thread, stabilzer, adhesive, etc.
Good luck in finding the machine you want, just be sure to do your homework ahead of time, and sew on as many machines as possible. My vote goes for a Bernina.
