You bring up a really good point. Since I have enough reserve funds to spend on a more expensive scope, I look at things in a different light then someone else. I look at it in the way of what can I get to lose the least value but still reasonably priced. So spending 500 when I can always sell it for 475 is smarter in my situation than 150 when I can only get back 100.So, while you're saving you... Do what? Don't hunt? Some guns don't have sights afterall.
And the point of the house analogy is that there are always people who have more money than you who don't understand how you can be foolish enough to spend less money on something than they do. It doesn't matter if it's a rifle scope, a car or a house. There's always "something" you can get for "just" double or triple the price that's an absolute "must have". Except, when you don't HAVE the money, you realize that they're NOT "must have".
It's pretty silly, I think, to suggest that a guy who can't afford a $450 scope should not hunt for 2 or 3 years while he saves money... and even $450 isn't expensive enough to be "good" for a lot of people.
Every post of mine might seem like I have a different opinion in each, but if you look at it closely they are really the same opinion, just expanding on the topic. If you can afford more expensive scopes, then it is usually worth it(even if just for resale value). If you cannot, don't be bullied by the optic snob's that think anything less than 750 is garbage and you need top of line as a beginner.
I have a $150 bsa, and just bought a vortex viper 6.5-24X50 which is said to have top level glass for anything under 800. So I will have to borrow my friends SLR camera and do a comparison for everyone.
