Hooray for you! What fun to play with the features of a new machine and good for you to get the table and other parts too. As advanced tool users we need not only good tools but good infrastructure and ergonomics too
I think the biggest improvement for me would be to have an actual sewing table so I could lower the machine to table height for quilting. I rather like top of the table for piecing just fine. Problem is I have a beast of a machine and a mouse of a budget but I am watching Craig's List. The other problem is that since I like piecing, I have a huge pile of tops and I've got to get better at getting them quilted down...
