My grandfather always taught me to buy the very best that I can afford. He also taught me that if I can't afford it now, save and afford it later. He always told me to buy quality and what I like. He said otherwise you will just keep buying lesser items due to unhappiness and lacking quality and performance and premature failure. He would instil this logic in me to almost everything. When I went to buy a pistol I could have afforded a springfield armory 1911. I waited over 2 years to afford a Les Baer Custom. I only have the one. I could not be happier. Thousands and thousands of rounds at the range, holster worn, MY pistol. Some may say its a collector gun, I say I saved and bought what I want. High end lasting goods tend to hold their resale value, this is another logic he always instilled in me.
If I want a 70$ GEC over the 35 dollar case I will save until I can afford it. I will buy the one I want and be happy. I will use it for everything and be satisfied. This is all such a personal thing. To me the logic of buying two cases instead of one GEC is almost a collectors type mindset. Just buy one GEC and use it.
Sometimes only the rich can afford to use expensive goods, but sometimes an average joe will save his pennies and get what he wants and really, can't afford NOT to use it.
This is just how I was raised.
