I just use my regular Brothers sewing machine. (7" throat). My BIL made a frame that allows the sewing machine to be moved over top of the quilt (almost like a long arm). The down side is that I can only quilt a strip of about 4-5 inches at a time... given the size of the throat of my sewing machine. So mostly I use a medium stippling or meandering. I am happy that for large quilts, I don't have to crawl on the floor to pin baste.
