I second Lightbrite about getting one from Costco. With relatively light use it should last a couple of years. We have a Brother we paid about 80 bucks for (I think it was on special). It started acting up a little lately, but can probably be repaired if we decide it’s worth it.
It’s been about five years, was never perfect when it came to button-holes or fancy stitches, but nevertheless a great buy.
