Bernina is too new to the longarm scene to have gotten everything right. I believe this month is their very first month on the market -- ever!!! Janome is another one that is too new for my blood, although they have been around a little longer than the Bernina.
Here is a link to a previous thread on the topic where you may find more info:

My advice is back off, back off, back off. A rule-of-thumb is to spend a year researching longarm options within your price range (and trying out machines for yourself at quilt shows) before making a decision. Seeing one demo is not going to give you a reasonable perspective.
