So...SIG saying, "we will price these to make the best profit we can" should impress you with their ethics! After all, there's little more a business could do to educate their customers than explain their pricing practices so clearly, right? Bravo to them.
And, of course, a buyer does not have to be uninformed OR overly emotional to pay a premium price for an item which may be available at a lower price point later on. Buying one now, at a few hundred dollars more than they will someday be worth, may simply not bother an educated buyer in the least.
There's no moral imperative to buy something as cheaply as it can be had, and no moral failure in spending money in a way that pleases you. I'm sure every one of us would grasp that we could buy a bottle of Pepsi from a vending machine for $1.50 right now, or we could drive to the super market and buy a six pack of those same bottles for $2.00 on sale. Most of us are going to put the buck fifty in the machine and enjoy our beverage. It isn't because we're uninformed or emotional.
