I am sure I would be considered a tool polisher by many because if I need a tool even once I will buy it (even if I may not need to use it again), and I will buy a nicer tool when a cheaper one will do for no other reason than it makes me happy to do so. My tools don't earn me money, so this has turned into me having a pretty nice collection of stuff compared to the average DIYer - some of which gets used frequently, but much of which gets used rarely. My tools don't make me money, so there is really not much practical reason to buy nicer stuff as opposed to Craftsman. I don't really care though, it makes me happy so I do it. And the other benefit is that you never know when you will need a tool in the future. An example - a year ago I got a few pairs of Knipex linesman pliers just because I found them for $7 new. Couldn't turn down that deal. Didn't use them for a year but the other day had to run a bunch of Romex and I was glad to have them.
Burn me at the stake if you want, I also "waste" money driving a BMW and going out to eat. In the end, nothing really matters unless it makes you happy.
