This is a video from HSN demonstrating the Brother HE-240 Sewing and Embroidery machine with USB port. The HE-240 is a private label that Brother made exclusively for HSN. It’s identical to the SE400 except perhaps for some accessories and bonuses HSN includes.
Don’t be put off by the price in the video. You can get the SE400 for more than $130 less at Amazon. If you want the bonuses, than buy the HE240 from HSN. But be sure to check the prices sold separately. HSN also offers a monthly payment plan which may be worth it to you. Otherwise your best buy is the Brother SE400 from Amazon.
