I do not understand this 'hobby' deal , I mean this is a business , this is not a hobby , if you are rich enough to consider this a hobby.
Compared to other hobbies this is quite cheap, Model Train hobbists spend THOUSANDS of dollars on set that "never ROI" Hell some people spend thousands of dollars for little lead figurines for a dice game of chance.
It's only around ~$25 for a single BE now including shipping, I think it's a perfectly reasonable hobby considering what others call "Hobbies"
