I love my Bernina 730 E...it does beautiful embroidery and quality stitches. The front loading bobbin is actually a plus if you embroider a lot or use the machine on a FMQ frame. The BSR feature is the icing on the cake. Bernina accessories are quite expensive, though.
My MIL has a embroidery Janome Memory Craft 8000, it is a very nice machine and the embroidery arm is far less bulky than other machines' embroidery attachments.
