Here's some equipment rules for a modern or futuristic setting . They were part of something I was working on but that project got a specific system for it and theses were written system agnostically and I'm not sure they have that much merit in the first place.
The idea was when you have a saturation of market options the ability to navigate brands and models becomes a character skill rather than a player skill.
Like if someone goes to buy a chainsaw and knows nothing about chainsaws they might by a shitty mid-range brand. If they know a little about chainsaws , they would seek out stihl or husqvarna.
If they know even more about chainsaws they would know which models from Stihl or Husqvarna are worth it and which are less so. At this stage of chainsaw knowledge they are likely to have formed an Opinion about if Stihl or Husqvarna are the better maker of chainsaws.
