My biggest issue is that the dysons of the world seem incredible but too expensive for my taste. And then, when you look for something else, you're either dealing with a ton of brands you never heard about that look like bad-quality chinese copies, or with inconsistency for metrics (AW? kPA?)

1. From all the things that I'm interested, what should I talk about?

2. Would anyone care about it enough to interact with me – because why would you speak something "out loud" if it wasn't for the purpose of the interaction/discussion?
