I am cheap. My stuff mostly is not. I'll wait for a sale to buy, but quality will last longer imo. I love a good bargain.
Flashlights are probably an exception - I carry 3-4 most of the time in different pockets and places in my go-kit, and I don't care which one I pull out and use, its usually only for a few minutes. By the same token I don't care if I hand them out and never get them back, but they always do. The modern Crees etc are just so much better than what I grew up with, they all have tremendous throws and lumens and stuff, I can't imagine that *I* really need a $100 model of anything like that. The Fenix models I've bought have all held up in rain and water so far. Same goes for headlamps, except I own one really good one (that's getting old) and a number of really inexpensive ones.
I have finally transitioned over to Eneloop rechargeables from earlier generation rechargeables and alkaline batteries, in all sizes except 9V and CR2032. More up front cost, but over time these become cheap to maintain. That doesn't stop me from spending $8 once a year on ~32ea AA alkalines and putting them in my emergency stash, on the off chance that I won't have electricity to recharge the Eneloops. I'll rotate those out every year or two and give them to my nephews, who still run on AAs.
I do buy inexpensive for potential giveaways - I bought a small stash of stocking caps the other day for $1 each, mostly to put on kids' heads at fire scenes. And I lose a lot of bandanas handing them out to folks who have been burned out of their homes.
