You got a great machine. I have the 630 with BSR and Embroidery. I did not touch the Embroidery stuff for about a year until I could get a class and learn how to use it. Come to think of it, I waited on the BSR until I could take a class too.
I like the front load bobbin, you can change it out with a quilt on the top of the machine, and it's easier to pop out.
