I have a Bernina 440 QE. It's been a deeeelight to sew on, but alllllllllllllll computerized machines are wayyy costly to fix if they have a problem with their "brain".
If you love you other machine (and want to keep it for a back up) I'd suggest starting to WATCH thrift stores, and even dealers. BUY a second used machine just for parts.
My back up machine is a 1977 Kenmore that I bought new in that year. It's been reliable beyond words through thick and thin. It sews muliple layers of Denim without a wobble. Ive made horse blankets with it, and I'd never do that to my Bernina.
Also, amazingly enough OVERSTOCK.COM has a lot of refurbished brandname machines. A friend of mine got a VERY NICE Janome for $100 off of Overstock last year. She has sewn purses with it and it's met every challenge. That was a heck of a deal!
