Yes to all of the above. My "collection" ranges from a cheap but works well $3 eBay AA zoomie to a 1/2 weeks pay (at the time) Surefire L2 to a rebuilt custom MagLite running 9 AA batteries, polished metal reflector, Pyrex glass lens, new switch & honest to god 1000L light when most were stunned by a 100L 123a light (for the better part of a full weeks pay w/OT). Had to have'em all when I bought'em. Everyone filled a need and/or a want. A couple might have stood out as the "best" at some point in the timeline by one standard or the other (bright, rugged, rare, etc) and all slip a bit farther from cutting edge with every new release. None have left me in the dark but all are just lights to me in the end. And this doesn't touch on the lights I have from before I was born that I can't leave behind at a yard/estate sale for a buck or two.
