Sorry I'm late here, must have been out in the shop. (lol). Anyways, I used the electroless nickel plating kit from Caswell and I was very happy with the results. That being said, considering the cost of the kit and the time involved preparing and plating the parts, I probably would have been better off sending the parts out to be finished.
But, I have spare time and I love experimenting so it was definately worth while.
