I would agree about getting a small Brother for a travel machine. I am a Baby Lock fan and have a Husqvarna for a travel machine. The machine is fine but it takes special feet just for the brand and things are different from the Baby Lock. I believe Bernina is a bit the same way in feet won't interchange with other brands, etc.
I should add I only paid $20 for the Husqvarna and that is why I bought it.
