When Viking brought out its 1st MegaQuilter 9", it came with an Inspira frame. I bought the machine but switched to a Grace Pro wood frame, just my preference. Don't see why you can't use any machine that will fit on the carriage. I added a PCQ robotic system to mine when I 1st got it, then used the same frame when I switched to a stretched Juki 18". Don't know how strong the Inspira frame is but be careful on how heavy the machine you'll be using on it so it doesn't bow it. If it has legs in the middle or every 3-4 feet, that should hold enough weight.

Any idea how much to sell my Inspira frame for? I have no idea.
