Apart from your search parameters being unfair with regards to proving your point as they produce a list with descending price order so that special expensive parts made for rough environments are listed on top, this "powerpc" search doesn't even find the more modern and more interesting Power Architecture parts like QorIQ T2080 or T4080.
