My suggestion is the Viking Mega Quilter. I love mine. It's really fast, has the knee lift and the thread cutter..it doesn't have the bobbin low message but other than that it is a great machine. I got mine on sale for 999. It's easy to load the bobbin and you don't have to take the quilt out to load it which is great. I use a good quality thread and have had no problems with thread breakage. It only does straight stitching so it is a no frill top of the line machine. My other machine is a Kenmore (made by Janome) but it doesn't have the thread cutter or knee lift but works great.
