[You get what you pay for]

I ordered two rebuild kits from Best and just got them today. They got here super fast. I installed them in two controllers that were flaky or not working at all. They work very well now. The PCBs are of very high quality.

Regarding the fire button issue you experienced, I ordered two fire buttons and two springs along with the rebuild kits. I figured it would be best for those two key parts to be new as well, along with the PCBs and the inner handles. I had no fire button issues. Yes, they are firm, and they make a loud click now, but they work just fine.
