I have the Sapphire 835 that I bought over 5 yrs ago. Never a problem with it.
It has tons of fancy stitchs but havnt used them and would have to look at the instructions to figure out how to use them.
It is not an embroidery machine.
It is oversized so not a travel machine.
It has a 1/4 in setting but still have to move the needle to get the right size blocks. Did buy a 1/4 in foot but dont use it anymore as you still have to move the needle. The regular foot works fine by moving the needle.
It came with a box of quilting stuff like a table and I think a walking foot that Joanns gave to me when I bought the machine.
Its a good machine and it has a 10 in throat space. I also like the auto foot raise when in needle down mode.
