I have the Weller WES 51, I like it a lot. The one Cheddar recommends looks fine. You will want one that has the temp display. I still have my old Hakko 808 for desoldiering. You will want something to do that job. Yes, you don't need to spend a million, but cheap stuff will only piss you off and more than likely you will replace it with something better. I'd say if your serious about fixing pinball machines including board work, skip the bottom feeder crap and go for the stuff recommended here. Just ran across this: https://www.amazon.com/Weller-WE1010NA-Digital-Soldering-Station/dp/B077JDGY1J/ref=dp_ob_title_hi It looks good too. Sticking with Weller or Hakko is a good idea.
