I have done a stitch in the ditch on the dinky under $100 Brother for a king sized quilt. I did what many above have done. Start in the middle and work out. I tried rolling (too much work) or puddling, which worked better. I did have to pull it through sometimes, but it didn't affect the finished product. I didn't even have a walking foot back then! That cheapy Costco machine keeps on trucking.
