I came across an interesting "blurb" about Karl Solie, CCIE #4599. As you may know, he's written a couple of lab books that cover an older blueprint, yet his books are still in demand. What I plan on doing is supplementing (as needed) Foundations and S2N with portions of his lab books. I'll match the relevant chapters from his books with the blueprint. These books are excellent and if you can find them at the right price, get them. Vendor lab books are expensive and this is a great way to learn and save.
