After accepting that I need quality crimpers I was finally ready to spend $60 on the Universal Micro Crimping Pliers - PA-09. But I have been waiting for many weeks and they are still out of stock.

Today I noticed Ratcheting Crimper Pliers - #18-28 AWG for only $35. Does anyone know how these two compare? From searching for the SN-28B model I found that it crimps in one step, unlike the 2 needed for the PA-09? But I also saw images of crimps from the SN-28B that looked like it caused the crimp metal to bite too deeply into the insulation of the wire. The JST pdf cautitoins against this Check points for perfect crimping.

Can anyone compare crimping quality between these two products from personal experience? I have no problem paying more for a better product! I am still holding out for Adafruit to restock the PA-09, I don't want to spend my money for them at a different retailer.

Also available is the Universal Crimping Pliers - PA-21, but since I figured I'd crimp more of the smaller wires I was holding out for the PA-09. There is also another ratcheting crimper Deluxe Crimping Tool from Hansen Hobbies, has only 2 crimp points.

The PA-09 covers a wider range of extra-teeny sizes, but only goes up to 20AWG. The ratcheting crimpers go up to 18AWG if that is important to you. In general, the ratcheting style tend to give you a more repeatable crimp, which is why they are used in industry. For non-production use, the ratcheting feature can sometimes be a handy 'third-hand' to hold the connector in place while you wrestle with an unruly wiring harness.

Thank you for the reply. But at the end of the day will there be a difference in the final quality of the crimps? Also, I am still leaning to get the PA-09 because of the smaller gauge, will you be finally restocking soon?

Thank you.
