I don't know enough about casting or anything involving a foundry to know how difficult it is, but My 100 lb Inch is 101 lbs (good) and my 125 lb is 119 lb (not so good). All in all I am happy with the outcome. The ordering process was easy, the turnaround time was reasonable considering the work that goes into, but they did show up a bit rough looking. All of that said, I will still be ordering from SSE in the future.
