So far all the reviews I have been able to find by Googling have been positive.
I ***loved*** the setup with the bigger harp machine when I tried it out at the show. If I already had a large harp machine like the Janome 1600p, I don't think I would have hesitated to buy it even though money is tight at the moment. Basically, $600 to have a comfortable free motion setup would be worth it! Just not sure as sure about $500 for the smaller setup for my regular-harp-sized Bernina. Plus, I'd have to move my Bernina between piecing and quilting (unless I could resign myself to using a vintage machine for piecing).
If money weren't so tight this year, I would have just purchased the larger setup *and* a new machine for quilting!
