I like the older too, the 530, a 730 is a favorite of mine, the 830 is well worth the effort too. The advantage with the 930 is the extra strong motor and the stretchy stitches, and clever functions in the pedal. There's absolutely no reason to put any of them down or up against each other. I have a 900 Nova, more portable and very nice too. The 930 has a more advanced electronic board, and I know the clever repair guys know how to solder on capasitors, repairs are worth it. Find the right guy and he/she will be able to fix it.
