Soldering Iron Kit, 100W High-Power LCD Digital Soldering Iron, Circuit Board Repair Soldering Kit with Magnifying Glass Helping Hands, Adjustable Temperature Solder Welding Tools

I just started with a cheap one on amazon. Look for a while kit that comes with solder, tweezers, desoldering pump, soldering tips, a basic sponge to clean tips, etc. A soldering iron at 90-100 WATTS is what you want for those thick ground pins on the joysticks. Something like this on Amazon $30 https://a.co/d/0bXsTChS
