If you like a shiney thread and a bargain try Metro Embroidery thread. I have used it in my LA with no problems whatsoever. It is very shiney, almost metallic.

Nice thread and dirt cheap, so inexpensive you can easily order nothing but the 5000 meter cones and not bat an eye at the cost. If I need an unusual color I go with it. My preferred thread is Glide which you can purchase direct from bobbincentral.com in larger quantities. Smaller you can purchase from quilts complete:

Edited to add, I rarely mess around with the 1000 meter minis unless it is a color I expect not to use much. So in your particular situation, are the colors ones that you think you will use again? If so then go with the big cones, if not try to order only what you need.
