I have a Bernina machine and overlocker, love them both...havent had them all that long though! lol
The woman I bought them from though has never had one returned, only serviced them. so thats good? lol

Anyway, I didnt have huge amounts to spend andI didnt want one with plastic mechanisms, so by passed the Brothers and a few people I know with Janomes werent impressed...And I was less than impressed with the Janome centre in Mandurah, so went the Bernina

Good luck!
