I've been lucky enough to test drive one, and I have to say, I want one!! But doing some research, I found
http://www.sunshine16.com/TakeIt.html which is more in my budget. I haven't found any dealers, and I emailed the website and Nancy said there aren't any in my area. However, all I've found about the sunshine is favorable. I'm saving up for it.
That having been said, you can quilt your king on your regular sewing machine! Um, there's all kinds of free info on the web on how to do that, but I learned a lot on a Craftsy course that was $20.
Good luck!
