I have a brother 1500
Pros
ONE stitch, STRAIGHT!
Knee lifter
Up and down needle position button
Feed dogs can be set at four different positions
Thread cutter button
"auto" needle threader
1500 stitches per minute
You can get one brand new for about 700.
Cons
doesn't have auto tension or a low bobbin warning, however it uses pretty large bobbins!
I love mine, however I have never been a Bernina owner. lol
