lol.
Did you select one yet?
There's an old saying: You can have it 1) Fast 2) Cheaply 3) High-Quality. Pick any two.
In your case 1) Fast... means less fiddling/easy-to-use.
So it's all a trade off of desires vs features.
Expense was a major factor for me. So is low-fiddle. Build-quality, not so much. Meh. I'd rather have 5 inexpensive mods over time than 1 high-priced one. You may be of the opposite opinion. You pick.
I went with a 510 when I started out and quickly moved into an eGo type of setup and rather quickly into mods from there. And DIY e-juice.
The biggest savings is in DIY e-juice. I vape for less than $.20 per day in juice costs (non-hardware). I also drip. Less problems, slightly more effort.
Getting a VV device is nice. It allows you to "tweak" the heat. Maybe start with a Spinner or Twist or some such. And a bunch of standard atomizers if you want to drip. Don't pay high prices for special "dripping attys" they are over-priced and over-rated, IMO. To be fair, I haven't tried all of them. But they are not necessary.
If you don't wish to drip, check out basic cartos and/or clearos 1st. See reviews. I'm using a dripping RDA right now so I can't make recommendations as to carto-of-the-month club.
Good Luck!
ETA: If you stay with e-cigs, the next "mod" could be a swappable battery setup. Keep the Spinner/Twist as a backup.
Also, if you insist on cig-a-likes, you can still drip if you wish. If not, at least fill your own cartos.
