I am a dyed in the wool, whole-grain, kinda gal. I had given up on whole grain pasta, because almost all of it (except homemade) had nasty, bitter flavours. Then, as I was shopping in my favourite Italian grocery store, I came across some whole grain pasta made in Italy. "Hmm, let's give this a try. Italians know how to make pasta." This was about 20 years ago. I have always had good luck with whole grain pasta made in Italy.My favorite spaghetti by far is from Trader Joe's, whole grain organic pasta. It's a little over a dollar a pound. Heck it may be made by one of the companies that you mention since it is a store brand.
I wasn't crazy about whole grain pasta until I bought this, I guess that it has improved over the years.
The one I usually buy costs ~$2.95/500 grams.
