I love ThreadArt thread - you get a lot for your money and it's really beautiful thread. I use it for free-motion embroidery and quilting and for garment sewing when I need a specific color.
Lots of companies (including Brother, I think) market this exact thread with their own brand name on it - it's the same thread, but the lowest cost of any I've seen.

There was just a thread about this the other day, so I probably sound like a broken record.
