For what it’s worth, I’ve managed to successfully mod a Game Boy Advance as a total soldering noob, with a cheap poor quality iron from Amazon. Some mods (particularly for home consoles) are difficult as all hell if you’re inexperienced, but the Game Boy tends to be fairly easy-going. There’s also an increasing number of mods (particularly screens) that are slightly more expensive, but are solder-less (or solder optional). Macho Nacho on YouTube covers quite a few of them. As for your buttons, you can buy new rubber membranes that make contact with the board to register the press. Give the board a good clean with isopropyl and pop some new membranes in and your buttons will no doubt be good as new—no soldering needed!
