Looking at the attachments and some accessories, Janome and HQ have to be working together on these machines. I guess they are going after the "name brand" market for those that are married to a specific brand of machine and won't buy one with a different name on it.
I like that they've now incorporated the front holder to hold the front rail out of the way when loading the quilt. HQ came up with an add on for older frames, and I wondered how long it would be before it was part of the frame.
