I have the Bertha cabinet for my large machine. It was hard to put togather and do not like the extensions on the side that have to be open as they do not lay down on the sides. The lift works very well and have not had problems but havnt really used it. I leave my machine in sewing position all the time. Im short so it is too tall for me and have to have my chair at the highest setting to sew. It cost $550 about 5 yrs ago. It also has a drop down table attached to the back so you have room for your quilt when quilting. It is 7 feet long when open and about 4 feet or more from the wall to the front of the table when the drop down is up. Takes up a lot of room but sure is nice to have.
