I have it and love it too. I originally got it to go with my Bernina 440. I know have an 830 and ordered a new acrylic inset and have problems with the way the machine sits. I know the 830 is much larger than a 440 but I wouldn't have thought I would be sitting up against the support where the lift control sits.
I'm going to have to have my insert custom made but I still think it's worth it. The only thing I wish I had done was gotten the extra 3 inches. I stand 5 ft 4 1/2 inches and I think it would be more comfortable to me.
Also, I might would have gone with the sewmate instead. I love having the extra storage but I end up losing the entire right hand side for quilting.
Otherwise I love my cabinet!!!
