Bernina vs Bernette Embroidery Machines

I'm planning to invest in a Beginner/intermediate embroidery machine. For a little side business.

I went to the Bernina shop and asked them about the difference between a bernina and a bernette embroidery machine. The staff said the bernina has a sturdier and higher quality build and it should last longer. I am no expert in embroidery machines (I used some high end stuff before in a professional work shop though) and I wonder if it's actually worth double the price to buy a bernina instead of a bernette (for entry/intermedate levels, for example Bernine B570 vs Bernette B79)

I'm looking for a second opinion, if anyone has some experience here?
