I was where you are about a month ago. I was looking to upgrade my 30-something Kenmore machine. I was convinced a Bernina was the way to go. They are high quality machines, however I couldn't justify the high price tag. I tried out several machines by different manufacturers, did my internet research and talked to quilters I know. I ended up with something else that gave me more bang for my buck and does everything I want/need it to do.
My suggestion would be to know what you need in a machine and test drive several before making your purchase.
Happy machine shopping!
