Hi Linda,
Congratulation with your new maschine. I have had my Bernina 830 for a year now and I LOVE it! Earlier I have had Bernina 440QE and 640.
I try to use all features on the maschine incl. the embroidery unit. I will very strongly recommend you to take some classes on how to use the 830. Now I do not know what maschine you used to work on but even for me who had quiet some Bernina experiences the classes have been very usefull.
The american Bernina web site has some tutorial, tips and tricks that are worth looking at. At their website you will also be able to find some achived web seminars that might be helpfull to you.
I am using my Bernina 830 for sewing, quilting, embroidering, applique (in the embroidery module), cutwork and punching.
So to your question - my Bernina 830 is definately my favorite. I also have a couple of FW that I like to use.
I am just a bit curious why your friend has sold the maschine.
If you have any questions, feel free to PM me.
Kind regards
Anne
