Yep, Fester is right...too much hassle to find Mr. 59X chip.
It will take at least 24X of what $$ he offered for a 58X chip (to find a few 57Xs or a 58X) unless you're lucky enough to find a 58X/59X with only a few purchases of 2600K.......or you can just spend your hard earned $$ to buy it from some peep:)
