I feel like every hobby has a high end no matter how cheap the entry cost. Aquariums can be cheap but you can get upwards of $100k invested.
I am into motorcycles and weight lifting, my first gym setup was $250 on Craigslist and my latest gym setup my wife and I built was over $50k. My first motorcycle was a ninja 650 from cycle trader for $1200 and 8 years later there are 4 Ducati’s and 2 KTMs in the garage. I feel if you truly get “into” something then it becomes and expensive hobby for sure.
I was trying to explain this to someone I work with the other day; I have a rule that I never question ones financial commitment to a hobby because no matter what if it’s important then everything goes out the window when it comes to money involved.
I am not into guns but some friends are, it’s not uncommon to have over $150,000 invested for the serious hobbyists! I have gamer friends that have spent over $20k on digital items and currency.
I was into fast cars a while back and spending money to mod them but switching to Tesla made me forget about buying anything else. :)
