Most people that ask this question regret asking in the end. However, it always comes up with a good list. I see we are missing Ladat, who makes some beautiful cases of the 'standard module'.
"Standard Module" is what anyone can buy from China and it is known as the 120 watt mini ZVS. There are only 3 makers that modified this circuit: DynaTec, Fluxer Heaters, and to an irrelevant degree, Alpine. All the rest use the same core module.
What I didn't see in the requirements was 'vape quality'. Tuning an IH is an opportunity often overlooked before judging the vape quality in an IH. Some devices allow tuning and some are even equipped with mechanism to adjust but this element is key to enjoyment of an IH.
I am in the camp of DIY the perfect IH. I got there and started taking some data. My feeling go out to ALL the makers. This is a tough subject matter under the hood. The variation of what vapors want and the variation in the magnetic coupling of the caps makes this a dartboard for the most part. Know this however, the more compact the the IH, the less forgiving it is. Those IHs that use the adapter as an insulator, those will have large coils and are very forgiving. If you don't like the profile at the click, see if the maker allows adjustments. PSM/Caldron does; Fluxer Heaters does; Mag Heaters has the adjustment built in - after that, the field dries up quickly. The idea is that tuning the click to the temperature can be achieved rather than adding seconds or worse, trying to pull early. You can get it to click pretty much spot on if know the option exists.
If you want a lifetime heater, you need lifetime support. As stated, DynaTec makes good products. They will fix Orion and the Apollo has been loved by many for years. Chris of DynaTec was one of the first to recognize the standard module was over-powered. DynaTec engineered their products for DynaVap VapCaps. Wired or battery powered, Apollo's make good desktop heaters with DV support.
@Pipes makes wonderful heaters with the Caldron as a desktop and he is available for support. A wonderful maker for many years here on FC. Fluxer heaters too went for what could be done. Today, Fluxer Heaters offers some of the most integrated heaters. All built into custom aluminum housings and interesting features. Fluxer Heater adds a power limiting option as well on some heaters and is working on including the desktop unit with this option.
I stop short of including 3D printed cases into the durable category. 3D prints are not durable in many respects. They rarely look good either. It will always be a piece of spaghetti wrapped into some kind of container. "Juice printer" is a next level quality where materials and implementation is critical. These boxes manage up to 100 watts - think about containing a 100 watt light bulb for the period you are firing. Nothing against the makers, really, but it must have its own subclass of induction heaters. I once sold a production product in a printed case - I made sure to express my humility in that regard. In that case, it was an appropriate use case to save on tooling that the product didn't warrant.
FC has been a wonderful resource for understanding these devices. Makers make this search all the more difficult with all their great offerings. VAS isn't for vapes only
One IH is never enough!
