Hmmm, there are soooooooooo many.
But considering staying in the Wismec Predator price range the Smoant Battlestar is a good all round work horse, it's easy to recommend this mod, most do, nice and compact, solid build, TC is pretty good too, instantly fires, can't go wrong.
The new Wismec Gen 3 is also probably their best to date, that's if your not put off by their other......not so good mods and this is a triple 18650 but is worth mentioning just for it's compact size. Both of those mods were posted above by KD.
There is also the Smoant Charon, another good mod, or if your looking for something lightweight, there's the Tesla WYE.
Smok mods - Alien, Smok GX2/4, Smok T Priv, although the paint did chip on mine but it works, TC could be better on them.
Another nice dual 18650 is the Eleaf Ikonn 220w, screen is a little dull but it's a good mod, firmware update could fix that.
There's the Sigelei Fuchai Duo 2/3, centered 510 and can fit 30mm tanks or the Sigelei KAOS Spectrum...
Voopoo drag, ignore the name ha, they do a resin version.....
In saying all that, personally, if I wanted one myself I would still go with either a Asmodus Minikin V2, battery life is amazing and a good mod, max of 25mm tanks but is slightly more expensive or the trusty Battlestar.
Going up in price there are obviously the Yihi and DNA chips/mods to consider.
The list goes on and on in this flooded market.
@Rooodie A bit of background into what mods you like might make it easier to recommend some to you because there are just way too many to list.
Agreed
I still stay, never charge any 18650 batteries via USB in the mod, no matter what new tech they say is in there, you simply cannot beat the safety and piece of mind of a external charger. Better to buy a 4 bay charger and some extra batteries, charge them up and pop them in a plastic 18650 box to take with you.
The only time I use USB is on my DNA lipo mods, cause well, some are sealed inside.
