I have the Brother NQ1400E, which I think is the precursor to your machine. I've been using it now for a couple of years, and it rarely sits idle. I've embroidered almost anything you can think of and it does a great job. It came with a 6x10 hoop and I added a 4x4 so I wouldn't always use so much stabilizer when working smaller designs.
I purchased thread sets from Amazon that come from an american company Thread Art. I have all of their colours (the price is very reasonable), so no matter what I want to stitch, I can find a colour that works. Although the thread is inexpensive, I rarely have a problem with it, and that's usually a user problem when the machine hasn't been threaded properly or the bobbin inserted properly or the needle needs to be changed.
Enjoy your machine. As my daughter says, "embroider all the things"
