I've knit Doodlepants, SheepyPants, and Perfection Pants. They are all nice patterns. Doodlepants is a very straightforward pattern with fewer details. The version I used lacked either a gusset or short rows, can't remember which. Perfection pants is a great pattern. More pictures, good explanation for getting the perfect fit, and easy to understand. My favorite is sheepy pants. Lots of pictures, lots of modifications, the BEST directions for short rows, and excellent pattern support. The gusset directions did give me trouble, but that was years ago, and it may be that the pattern's been updated. I believe it's also (last I checked) about half the price of the Perfection Pants pattern.
