I suppose I have the luxury of not worry much about the cost of a product. I'll spend more money if it works. My primary concern is that it works for me (YMMV) and it can be easily replaced when I use it up in training or reality on short notice, like within a couple hours.

When researching a product I am especially concerned about replacement cost and location. It is for this reason I buy off the shelf. Only online if I have handled the product and the price is unbeatable.

I do not abide by having 1 item for show and 1 for go.
