I have a bernina bernette 92c. Love her to bits! Cost about $600 I think but it isn't the base model.
I have a bernina overlocker too and they are both easy to use and very good quality.
Steer clear of Brothers.
I got the Bernina because they were better than Janomes from the reviews I had heard and better value. But the janome and bernina were the only places I had near me to get parts, serviced etc. Something to consider when buying is the cost and ease of servicing and parts, advice and lessons on how to use it when you first get it.
