I personally like Aspire's original Triton with a 1.8Ω coil. It delivers good flavour. There will probably be those who'll scream 'NO! don't go there!' Some folks have reported that they leak like sieves. I have six of them. Two came directly from Aspire, four 'leaky' tanks were acquired locally. The most I paid for the 'leaky' tanks was $5.00, and two were free. Three of them worked perfectly (no leaks) after a cleaning and replacement of the coil. The last needed a new seal at the top of the chimney. An alternate, if you don't want to go there, is Aspire's Atlantis. Get the 510 drip tip adapter, and a drip tip with this tank for mouth to lung vaping. These tanks can use all of Aspire's coils for the Atlantis or Triton series. The new 0.5Ω Clapton coil is very good. You'll want to use this coil when your 2yr old is abed because it produces lots of "smoke fire."
For a MOD, I'd recommend any of the single 18650, or built-in battery name brands, that are TC capable and can go up to at least 70 watts. Over 70 watts you'll want a twin 18650 MOD. The MOD should be adjustable in 0.1 watt and 5° increments, depending on the mode. Go to a local shop, and check the controls of the mod before you buy it. I don't like my Sigelei 150W because the power changes too quickly. It's hard to get a certain power level. I don't like Aspire's Pegasus, as the power is only adjustable in one watt increments. The original Pegasus with it's automatic coil detection is one MOD you should stay as far away from as you can. The new Smok X-Cube mini is worth a look, but only if you have an iphone 4s or newer. The Smok BEC app for Android would not communicate with my X-Cube 2.
The best advise i can give you is to wait for reviews to come out, and check the forums for any problems, before buying ANY equipment new to the market.
