Ok, I'm convinced and just ordered the one attached below.
It's a 3L, 120W US power, 100W heating power, with a 99 minutes timer.

I should have it next week. It should be big enough to steep my juices (I can't wait 2-3 weeks before testing my recipes, and it costs me 30€ per week of juice - I used to smoke for less than 10€/month of tobacco in my joints, no way vaping should cost me more than smoking !!!), as well as making my own THC juice and experimenting with extractions (DMT).

Can't wait to test it, thank you very much for all the great info.

In the vaping community, there's a lot of ego fighting about US steeping, but at least here, if a fellow hyperspace traveller/chemist tells me it works, then I believe it

I must admit I'm having a lot of fun creating my own juices recipes, as always, I have peculiar tastes, and there are only a handful of commercial juices that I like, so DIY ejuice is clearly the way to go for me. It's a logical step, I've been growing my own cannabis for 25 years, my own mushrooms, extract DMT/harmalas, grow my tomatoes, it's absurd to not do my own juice. I like to be the master of my own experiences.

Is it useful to ultrasonically steep my DMT juice ? Or better to ultrasonically steep some flavours, then just add DMT in a hot bath without ultrasounds ?
