Hi Lori!
I have an 830. It is my first sewing machine--I have had it a little over a year now. I purchased it after retiring with the thought that quilting attracted me. I was looking at a 440QE and was ready to put my money down on it, fearing that purchasing the 830 was too big an investment if I did not pursue quilting in earnest. My husband, wisely, suggested that I would outgrow the 440 in six months and that I should seriously consider the 830, especially since I had no thought of considering a mid-arm or long-arm machine in the near (or even distant) future and was determined to learn free-motion quilting. He also suggested that I was too old to work my way up the machine hierarchy and that I should start at the top
(he was right, there too, glad I listened...).
What I really love about this machine is the throat space--very convenient for moving big pieces of fabric around in free-motion. I also like the features: a tap of the foot pedal or the button on the front of the machine will bring the presser foot down on my work to start; I can pre-program securing stitches, cutting the thread automatically and raising the presser foot after the thread cut and the list goes on regarding what I can pre-program. Directional sewing gives me the ability to do decorative stitches that are larger than the 9mm throat plate. I can take any set of decorative stitches and combine them. The extension feature allows me to extend the length of a decorative stitch if I need to in order to have the decorative pattern end as a full pattern where I want it to on the line I want to stitch. I have found great use for the dual-feed feature--personally, I like it even more than the walking foot. I use it for attaching binding, piecing blocks and even stitch in the ditch (when not doing it free motion). I can transfer decorative stitch combinations to the embroidery side of the machine to stitch straighter lines of decorative stitches in the hoop. I won't go into the embroidery side of the machine (which I love), but suffice it to say, I have the V6 software which allows me to make my own designs which I am very, very happy to send to the 830 with a USB stick.
In my first six months of owning the machine, I made just about every mistake in the book and have even jammed thread in the bobbin case (lots of thread) with the needle in the down position and the fabric sucked into the throat plate with the hoop in place… My Bernina dealer is wonderful and took a lot of HELP phone calls from me for a while. But, remember, I never owned a sewing machine before this one and I made just about every possible mistake you read about when people complain about the 830. After a little over a year, in my case, I can say with confidence that every problem I had with the 830 was operator error! I am convinced that higher-end machines are more sensitive and we need to learn to 'drive' this machine a little differently than some of the others, like the 440QE. For example, most people tap on the pedal to bring the needle down and tap again to bring the bobbin thread up to the top. With the 830, you need to tap with your heel on the part of the pedal closest to you to do that. If you just tap on the pedal, you might get lucky a couple of times… but you risk getting the bobbin thread and top thread all garbled and balled up together inside the bobbin case, jamming everything like I did. It's been a long time since I've called my Bernina dealer for help.
What I found most useful in learning my machine were the Video Mastery Guide Classes available on line. I've watched them over and over and done the practice sessions the presenter provides. I've also taken a project or two from the Bernina website and done those to learn special features of the machine and improve my knowledge of the 830.
I no longer have misgivings about what I spent for the 830. Now, when I visit my sister and use her 440QE, I can't wait to get back to my 830…
Hope this helps.
