Interestingly enough, many of them invest $5K or more in TVs/screens, cars, motorcycles, dinning and on so many other areas (some questionable) without a doubt.
This hobby is a selfish one, 75% of the time I listen to it is me in front of my Guarneri's allocated in my "nothing-box", I have a year or so with a 100 inch projector and have seen 5 movies so far with my family, with whom I spend A LOT of time traveling, dinning and having a great time together.
For me this hobby is destinated to be small, very small.
