If I ran a forum it would be against the rules to talk shit about other people "over paying or paying too much" for gear because honestly I want people to contribute information, pics or clips about bad ass gear. People talking shit because in their "opinion" they think something is way overvalued and anyone paying "X" amount is stupid keeps people from talking about or sharing information about gear we normally would not hear about.
This is part of the reason you don't normally see big time artist or producers regularly contributing to online forums because of the shit they would get from haters or people who would never be able to afford high end gear which is a shame.
Also those 30k or 999k listing are looking for people to make serious offers, they obviously are not looking to get that price otherwise they would not have a best offer option available.
Awesome score on that Fish and that Diezel. I was actually looking at both of those. Congrats to the buyers and I would like to hear more about your purchase after you have a chance to play through them.
