I have a Nolting & I love it. I have never had any problems with it. I was like you with doubts, but so glad I got my Nolting. I tried several different brands at a guilt show & decided on my Nolting because of the simplicity. You really don't need a lot of bells & whistles. And they are easy to maneuver. Not as heavy as some.
Hope this helps & enjoy your new machine.
