I'm thinking Bernina might be out of your price range. I really thought I wanted one. Maybe someday, but i will have to be convinced ;-) I have the MC6600 Janome. It cost me $1500 nearly 8 years ago and has held its value.
My advice is to look. Don't go to buy. Try everything out. Make notes. Go home and think about it. Search the internet. Make your decision after research. Going to a show doesn't mean you have to walk home with a machine. There are so many good options. Take your time. It's a big investment.
