For many years I used several Longarm quilters in the area, was able purchase a Gammill after my mom passed away, then updating to a Statler 5 yrs later.
I have a friend who purchase a Viking with a table of sorts, but she is unable to quilt even with a Q Bot in the 4 or so inch area she has to work in.
I make around 10 full-king size quilts a year, so that is one reason I purchased a longarm, and my mom really wanted my sister and I to have one.
I have even tied a couple with my LA table... two double knit quilts.
If you have heard of the Flynn system, I have hand quilted with that also. It works great.
