I think the issue of discussing how other people spend their money (whether earned or borrowed) and what they spend it on, is getting out of hand in CS.
there was a equipment talk on whether SLR is needed it take good pics, then there was the "famous" expensive lens Vs cheap lens talk, then there was one on borrowing money for hobby talk.....
blah blah blah....
In every one's heart, different things ranked differently in different phase of our lifes.
For me, maybe bikking is ranked above photography and I will sell my spare lens for a good bike frame, for others they may sell their cameras to buy a car....etc
Who are we to say another people's spending habits is crazy?
I am sure all of us have bought some thing expensive which other people around him felt it was crazy to do so in his life.
branded watches, Jeans, LV wallets, DSLRs, bicycles, hi-fi...etc
