The good news it that because the canister lights (and many other tech items) are of high quality, you can get an excellent light for much less money if you buy 2nd hand.
Lots of people upgrade as their diving advances, or they buy extras when they can afford it, then sell extras when they hit a financial rough spot, want to buy something really expensive, like a rebreather or a compressor. Tech diving is full of guys that love having the newest & best stuff, then sell the same items at a huge discount just a few years later because they have already bought 1-2 comparable items that are newer and better. I love these people! And at least occasionally I probably resemble these people
