Hard to get user ratings as different features are of different importance to individuals.
OK, to stop smoking and mimic a cigarette, you'll go with something very different than the big mod, big cloud direction. I mean, you could, but it probably won't work as well and be more of a headache than a help. That said, you can start off dead simple and get what you're looking for for far less than your current budget.
The simplest and what I believe more and more for a new vaper (which you sorta are) is to consider a pod mod. They mimic a cigarette, and many can be refilled so you're not tied into expensive pod of juice you through in no time. Affordable, portable, and if you just want plug and play, the way to go. There is a whole pod mod section here that's worth reading through where you will get individual's ratings.
If you want something a bit more flexible than a pod mod, you can get an inexpensive mod for under $50 (under $30 for that matter) which will be more than sufficient for a lower power, mtl setup which mimics a cigarette. The Pico is very popular and requires only one replaceable battery. Only drawback is no tank over 23 mm, which with all the 25 mm tanks coming out might be an issue. The is a new, larger Pico being released which will take a 25 mm deck, but it will be a different build and no idea on quality yet.
Tanks are fairly straightforward. There is the popular Nauti series coil tanks which work really well for mtl use. There is a new Nautilus 2 out which folks sorta like, but I would go with the slightly older Triton mini which uses Nautilus coils and is top fill. Dead simple to use and great performance. Other newer mtl tanks on the market include the Smok Spirals, and a Sense Blazer mini. I'm sure others will pipe up with more options.
As to juice and nic levels, how much are you currently smoking?
