I recently purchased a Bernina 580. No, I wouldn't do it again. I do a lot of machine embroidery with this machine.
It's pinicky about threads. The way it is designed, it is easy to get thread caught up in the thread uptake bar. You have to take the machine cover off of the machine to get the thread out. It must be a common problem as they have the topic on getting the threads caught in there out in the manual. Mine had to go in for repairs the first week I had it. The thread can get caught inside the bobbin case. The thread sensors tell me I'm out of thread or broken thread messages when the thread is not broken or I still have a ton of thread on the bobbin or top thread. So it constantly stops sewing.
The thing that actually drives me buggy is that you have to go through several screens to get to the function you want.
My Bernina 180 is fantastic.
My Bernina 1090 alsos fantastic and is the one I use for patchwork and quilting and is still going strong after too many years to count.
