I bought Salvo lights when that company existed. Some of the folks from Salvo founded Light Monkey. So I have been dealing with these people for nine years now, and although they build very good lights, it isn't the lights themselves that keep me a loyal LM customer. It's the insane customer service you get on the rare occasions when you need it. I've had them come in on weekend days that they don't normally work, in order to get a repaired light to someone who was bringing it home to me. I've had them FedEx me a latch at THEIR expense because one broke just before a big dive trip. They do a lot of stuff for nothing, and when they do charge you for repairs or upgrades, the costs are modest. I love them; they tinker and innovate all the time, and if I could come up with a good reason for another light (we have four of them) I'd buy one of the LEDs with the split canister, to run a light and heater.
