Ahh .. it was her blog, not a forum. This is the original article she posted about the subject.

I DO understand what she's saying ... in some cases, one machine may not be enough to satisfy you but she never once says that you MUST have two machines to do piecing and quilting. She said that at the time, in 2009, that was her preference.
My experience when I was using low end machines was pretty much the same actually ... One machine did not do everything I needed. The machines that exist today have pretty much made that a thing of the past ...
