I don't much care about price. Factoring in time is what I look at. The time to replace. The time involved in ordering it. Also, "works better" is very subjective. I've been using headlamps daily in the leather shop since I started doing leather work as a hobby. I generally get six months out of an elastic headband. I don't expect more. I spend the next six months just dealing with it, until I buy a new headlamp with better efficiency so it won't shut off in the middle of something. It's why I have really wanted HDS to come out with a headlamp.
I won't use elastic or Velcro in anything I make because I offer a lifetime warranty. My lifetime. When I'm dead, your warranty ends. So I try to make everything so it will last longer than me, and unfortunately, according to my family gene pool, I'll be around to my mid 90's though I'm doing just about everything in my power to avoid staying on this spinning rock that long much to the dismay of my doctor.
For me, a lot of the goods I buy, I only want to buy once unless it is disposable. Even my water filter is good for 6000 gallons, and at a gallon a day for drinking, I won't have to replace the filters for 16 years. Damn. I'll have to replace them in another 6.
