I use a wee mech squonker and single coil atty as my day to day vape and it suits me to a tee, but it doesn't suit everyone. Squonking has never been more accessible - there's a plethora of mods and attys to suit all styles of vaping available nowadays.
Basium is a very decent mod, I had one last summer for a few months and really enjoyed it - given the choice today though and it'd be the Topside dual purely for the super easy fill system and 10ml capacity. They both basically have the same chip, so it's essentially different clothes and the choice of a fiddly to fill 6ml capacity, or a very easy 10ml capacity?
I'd also recommend getting a single coil RDA to begin with - learn to build and wick on a single coil until you you get used to it/become proficient at it; there's plenty of good cheap single coil RDAs on the market from tight mouth to lung, to pretty airy lung hitters. Move on to a dual coiler when you're ready - dual coils are a bit more tricky to set up and get firing evenly, your coils need to be identical which can be tricky if you're just starting out wrapping your own. Also dual coils halves the resistance of your build, which you need to be aware of (and so on depending how many coils you fit in atty - three coils fitted and your resistance will be a third of a single coil, four coils will be a quarter etc) no big deal on a regulated device, but it can have a major impact on battery life and liquid consumption when what you thought was going to be a 0.5 ohm build is actually 0.25 and you need to crank the wattage for a decent vape.
You really need to do the hard miles with rebuildables, aye there are shortcuts you can take like buying pre-made coils (I buy them now as I like chunky coils that are a PITA to make) but fitting, bedding in, and wicking are things that only improve with experience - also some people are more adept than others with things like this and I wouldn't dare be presumptuous as to your abilities, but if you can wire a plug you'll be fine, your just wiring a smaller plug!
