Quote: The D&D kit seems to be the same as the TPUSA kit, only cheaper. The CR's available are different & the TP kit comes with clutch springs, but even when added to the D&D kit it still comes in cheaper.
Any reason why?
TPUSA cams are cheaper though...
I am pretty happy with the D&D kit and the people there are very helpful with any questions.
