i must agree that bobbin central is the place to go. i don't have a LA yet, going to start with a Juki 2010Q for now and adapt and go from there as monies allow. however, i do quilt with my janome which is just a home machine no biggie no whistles and bells and only a 5" throat space. i have used so fine, aurfil, connecting threads lines, and sulky. glide is hands down my favorite. it is virtually painless to use since i am "handicapped" to begin with with bulky gloves and a small work area, i have found it to be the best. bobbin central is dirt cheap ~ you must place a $35 order to order from them, but the 5k spools average 7 and i have seen them for 6 for black or white. have fun shopping! glide is smooth, slightly silky textured, and doesn't leave lint!
