I gotta say compared to most hobbies, scale auto modeling if fairly low buck. My RC pals spend WAY more than I do. Heck, the average weekend golfer spends more per year than I do.
On the whole I got no complaints. The increased kit prices we're seeing lately I don't even bat an eye at. I look at it as entertainment and enjoyment over time, considering it takes me 6 months to finish a model. I also have a very small stash, just 53 kits including WIPs. I don't buy because it's a great kit, or it's a new kit. I buy either because it's a model that speaks to me and I have an idea for it, or because I need parts from it. And I almost never buy multiples. The Revell '67 Charger is the sole exception to that rule.
