When someone loves to do something they have every right to spend large amounts of money they earned on it. Sure you criticize him for spending 1k but I can just as easily criticize you forum users who spend $1,000-$2,000 on computers.
I've spent up to $3,000 when I bought my ATV and $1,400 completely redoing the sound system in my car. Do you know why? Working on my car and riding my ATV are things I enjoy doing. I work, therefore I have the right to spend my money on the things I love.
Kilser is no different.
