I just bought a mostly Blackhawk set with Proto breaker and one Snap-On extension for $125 +$5 because I didn’t have change. It was an exceptional deal, and I might would have paid $500-$600 for it if I needed it. My old set is hodge-lodge Wright, Bonney, Snap-On, Proto, S-K, etc. I’ve got one Vlchek socket cracked. I seldom see big wrenches or sockets break. Many of mine have been ground down to fit somewhere. They are tools, I use and abuse them. Value really depends on how much the purchaser needs or wants them.
