Buy just one, give it a thorough run and see if the bird's nests are gone. Now, as much as I LOVE my 6600, she is a thread diva. She will chew up and spit out Gutterman and Coats and Clarks, but, sings like a canary when using Mettler or Aurafil. As much as I love these machines, if the bird's nests still occur then I might try a bobbin washer. Janome had isssues with their bobbins in the 6500 & 6600s and were supposed to rectify that problem with the 7700. Anyway, yes they are finicky machines, but, I still wouldn't trade her. I have a brand new Husquvarna Sapphire 875 that my DH bought me last summer, and I still prefer my Janome. Good luck and let us know how you make out.
I agree to a point ... yes our 6600's can be thread divas - and if truth be told I LIKE it that way because my machine TAUGHT ME about thread so to speak.
My machine however likes Gutterman!!
Most of the time I use Aurifil - that's my favorite, but I use Gutterman in the bobbin quite often, and I will use it in the top as well.
It *could* still be your machine. If nothing else, you should be able to use the Gutterman in the bobbin.
