I'm not sure about price gouging, necessarily. I might be speculating here a bit, but they were (are) in a hole that they needed to dig out of financially. I read somewhere that part of their financial problem was they were selling kits for BELOW cost (particularly the QB's coming from overseas) and didn't realize it. Their eye clearly was not on the financial ball - probably didn't have the right people in place to manage what had become a behemoth very quickly. So from that perspective, some builders probably got great deals on kits and didn't know it - the pricing in affect at the time didn't reflect the true cost/profit margin that Van's needed to stay healthy in business long term.
That's my perspective on kit price increases. Yep, I'm glad I'm not building at this moment in time because it would be a lot more expensive than it was for me just a few years ago. And I'm REALLY thankful my plane was already complete and flying during the bankruptcy as they were trying to get thing figured out. I know parts delivery was frustrating for lots of people during that time. But if I were building now, I'd somehow stay the course. Because I have the luxury of knowing what I'd be building is a great, well-designed, brand new airplane with great performance and incredible handling and looks. I'm reminded of this every time I open the hangar door and especially when I pull it out of the hangar fly it.
It's an expensive hobby, and getting more so. But still, in my opinion, this is the least expensive way to own a brand new, fast airplane, capable, cross county airplane. And I can work on it, too, so I don't have to pay someone to do it and incur that expense.
