I use Metro Pro Thread almost exclusively...I have all of the 5,000m cones and most of the 1000m cones in all colors. I have used this thread for over 12 years and have never had a problem. I also use their stabilizers and pre-wound bobbins. I have never found a better quality, sheen or value for any of their items elsewhere. There customer service is excellent and if you do encounter a problem, they are very prompt in fixing it. I can't recommend them enough. Here is a link if you are interested in checking out their products:
