My first LED light (other than those 9LED jobbies) was a streamlight polytac followed almost instantly (as in less that a week) by a quark pro 2AA and an (orignal run) Pink preon P1 for the wife.
Then within a few months of getting them I purchased an original RGBW quark for $55 off CPF, played with it a little, put it in its box and left it till about this time last year when I sold it on eBay (paired with an now very rare 18650 quark body) for ~$175!
To this day that’s the best mark-up I’ve made on any light and it was totally stock.
