The Margo Anderson patterns are A+++ and well worth the price. Not only do they come with the patterns (which are amazingly easy to use), they also come with like over one hundred pages worth of instructions / documentation that's in depth and easy to follow. I have their Loose Gown pattern, and my friend has a couple of the other Elizabethan pattern. They are well worth the money.
The Tudor Tailor...kind of has instructions? It really isn't a pattern pattern so much as its the basic shape drawn out on grids - so its very general. It mentions somewhere in the book what the scale of the patterns is, but I can't for the life of me recall what it is off the top of my head.
