Yes, those Nightshade volumes are incredible. I've got them all, and I enjoy them greatly. CAS is my favorite of the Big Three when I am reading his work . . . but then I change my mind and say HPL when I am reading his work. But I cut my teeth on the works of REH, and when I am reading his work, it feels like a punch to the gut and like home all at the same time. Recently I finally read all the El Borak tales, and my infatuation with Howard's fiction and poetry was rekindled.
