The AMP brand crimper is a high quality crimper that has interchangable dies, and the modular plug inserts from the front of the unit not the side, so either hand should work fine. I've used it for years with no trouble, it is a ratcheting type tool and very sturdy.
Good Luck!
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!
