I suffer most from Being excessive in better quality alone. Not so much buying quantities that I won't use.
Perfect example, I feel I will be needing a new air compressor soon as my 3 gal craftsman is on the fritz. The regulator is stuck in a usable position, the on/off switch swings around freely past all stops so you can't ever really tell if it's off until you bleed it down past the start pressure and it stays off, and the drain plug knob broke off so only ways to bleed it down is through the hose and then get a set of pliers to loosen the drain stem. This obviously won't work forever as the stem is getting pretty messed up already.
Anyways the little compressor has served me well for a decade and only a couple of times was I using an air drill or impact and had to wait, wait, wait to air to rebuild. I could probably get away with a 20 gal craftsman again.
But NO, what do I do? I research until I'm blue in the face and am contemplating an IR 60 gal 5SL5 for maybe 2-3 dozen uses per year. Can't help it. The Internet is full of too much information and stores have made it all too easy. Add to cart, proceed to checkout; your item will be on your front door step in 3-5 days. Amazing, but dangerous for guys like me.
