I use this exact same one. It can be a little fussy and take a bit of practice to figure out which crimping die to use, and I still don't think it's working like it should.

G-P-E had recently suggested picking up a used Molex brand crimper on eBay for something like $30 or $40. Full price new is something like $150, so I think it may be a worthwhile search for perfect crimps.

After extensive research and testing, I have found that the absolute best wire stripper is a Stripmaster (45-292) made by Ideal.

They sell several versions of this tool depending on wire size and type. I can confirm that the tool itself is identical and only the replaceable cutting dies are different. I have two of these, one for 10 to 22 AWG wire and one for Coax cable. The cutting dies are fully interchangeable.

I picked one up at Menards on sale 50% off for $20 and the other on eBay for about $10, which was cheaper than the dies I needed. I got lucky, but I would have gladly paid full retail of $40 had I not found these deals.
