NEED- 6 Needle or larger Embroidery Machine- Prefer Brother or Babylock

I currently own a low hour Babylock BMP8. I am looking to purchase a second machine so I can do two things at once.

Here is what I need:
Minimum of 6 colors
Somewhat near Greenville SC or something that can be shipped
MUST have USB capability-- NO CABLES, MUST work with a flash drive

I would prefer a BMP6 upgraded version, a BMP 8, or a BMP9. OR the Brother versions (PR650, etc) so I can interchange supplies and hoops.

When I bought my first one I paid $4000 and that included shipping, gold standard warranty, servicing, a stand, 2 sets of hoops and cat/hap driver. I am not interested in paying more than what I paid last year for less of a product!

Thanks!!! If you have something and we can work out a deal, here is my email:
