Welcome to ECF and the world of vaping! Sounds like you're doing great so far.
Your device is rather dated, which isn't a problem in itself if it's working for you. Many of us older members also quit cigarettes with something similar. However, there may be a downside. If I recall correctly, that style of device had a higher risk of producing some substances we'd rather not inhale. Don't be scared off - it's still much, much less harmful than cigarettes, but a more modern device might be safer still.
If you'd like to look at your options for replacement, I'll start by explaining that there are currently three styles of vaping:
- Pod mods - tiny devices, low airflow, use a tiny bit of juice per puff so the juice tends to have very high levels of nicotine
- MTL (mouth-to-lung) - middle of the road option - moderate airflow, moderate juice usage, moderate nicotine levels
- DL (direct lung) - the heavy hitter - high airflow, goes through a lot of juice per puff so nicotine levels are lower
As you like what you've got, I'd recommend MTL-style vaping for you. It's the most similar. And for MTL vaping, you'll need a tank and a mod (they often come together as a set). Concerning the mod, the first question is whether you want an internal battery mod or a replaceable battery mod.
Internal battery - The battery is part of the mod. They're charged by USB, and you just plug it in to charge. They're usually a bit cheaper at the outset and you don't need to buy an external charger. The downside is that when the mod dies you have to replace the whole thing. Additionally, the USB port tends to be a weak point, and if it goes the whole thing is toast.
Replaceable battery - There's a battery you can take out of the mod to recharge (you can also recharge it in the mod, but that's not recommend as a regular practice). You need to buy more things at the start - the mod, two or four batteries, an external charger - but when the battery or the mod dies you only need to replace whatever perished and not the whole thing, so it can be less expensive in the long run. You don't use the USB port as much (or at all), so you're not dependent on its lifespan. Note that if you do take this option, please ask us for advice on batteries. There are a number of factors that go in to selecting an appropriate battery, but vape shop employees don't tend to be well-informed. ECF, on the other hand, will be happy to point you to the right battery and the right place to buy it from.
As far as tanks go, I'd strongly recommend one of these two:
- Innokin Zenith or Zlide
- Aspire Nautilus - There are several versions, but you might want to start with the Nautilus 2

I've linked to the manufacturers' sites, but you can usually find things at better prices elsewhere.
In any case, good luck and congratulations on switching to vaping!
