They advertise a rebuilt box with 2.5 turns lock to lock for about $300. P/N CP6537Q

Detroit Speed's 600 series box is $500

AGR's is $350 (only another $50 retail compared to the CPP box, but about a $100 difference in what I can get it for ).

So is the CPP box any good? Anyone have one in service now? Doesn't bother me at all that it's a rebuilt unit, but it is going to be daily driven.
