I do not have experience with that machine, but Bernina has a good reputation.
When I bought my used mid-arm machine w/hydraulic lift table, I also knew it had been very lightly used. Big plus! She decided a long arm was what she would rather have. I had the benefit of trying a Sweet 16 midarm machine at the Original Sewing & Quilt Expo in the Twin Cities, so I knew I would like it.
Hope you are able to get it and enjoy it as much as I have my machine! Happy quilting!
