I buy what I can for machine quilting. My 2662 and 401 don't seem to be too picky. I just find as long as I have the right needle, I'm good. Just gave my machines a good cleaning and the 401 a good maintenance (oil/lube). DH stopped by JoAnn's for some upholstery to fix back seat of his truck. Headed straight for the 401 did what he needed to do. When he was finished, he gave it a pat and said "Good girl". He also picked up the thread for the machine to use set the cam to use. He just did it like a pro. He picked up extra needles. Now I have about 11 packs of needles for the 401 and the 2662. He loves those machine but the 401 is his favorite.
