Someone is advertising a used one for sale for what seems to be a good price. Does anyone here own one? I am especially interested in whether it has adjustable foot pressure, drop in bobbin and can handle a wide variety of fabric thicknesses. I read some online reviews, a couple of which didn’t like the ball used to make selections, and the glare from the screen. How long have you had your machine and how much usage does it get? I need a workhorse that will hold up a long time and this machine’s strengths appear to be its versatility for fancy things I rarely, if ever, do. Thanks for any feedback you can give.
