If you end up getting the ProTanks be sure to spend an extra couple of bucks and order the air flow controls valves to go with them. It's a big improvement over a PT without it.
One of my biggest regrets is that I didn't spend the extra 10 or 20 dollars to get better equipment to start. I ended up wasting more money. I agree on the adjustable air flow for the tanks. I am familiar with the Aspire ET-S is comparable to the protank and a little cheaper. The 50W iStick is only $15 more than the 30W. (remember to get a 510 to ego adapter $5, if you go inexpensive tanks) I'd recommend the 50W and a Nautilus Mini.
If it doesn't work they are easy to get rid of, or have as a back up.
I don't regret a single one of those "mistakes". I learned something from every one of them.
I will say, that because of those mistakes, I now know how to get my preferred vape from just about anything that you would care to hand me.
IMO there isn't, and never will be, a "Perfect set up for someone about to make the switch for the first time" because what was perfect for me probably wouldn't be perfect for you.
