The gauge for Big Wool seems to be 8 stitches to 4". I am getting the same gauge, and in fact the same gauge is listed, for Filatura di Crosa "Super Soft", which is now on sale at Webs for $2.99 for a 50 gram ball.
I'll go check out the Super Soft at Web's. I know that I already like the price. Oh, I guess that I should said that I'm looking at the pattern for the turtleneck poncho in "Stitch N' Bitch".
