Just get a ratchet crimper (China OEM or original) because you'll die using a normal $15 (when not overpriced) crimper. The average $15- $20 crimpers you see in shops are only good for 100+ crimps before dying (assuming your palms haven't blistered by then). Tested and proven by my ex-colleague.
He went through 4 of those for 200+ cables (~400 odd heads) before shelling out $200 for his Tyco crimper. I settled for a $70 ratchet crimper from UHF technology in SLS. They also carry the China OEM of the Tyco crimper for $88.
